I believe Jarvis is still way ahead what we currently have. Or at least most of what we have. He's incredibly intuitive and performs many functions with ease. It's also impressive how well he can be transferred to other computing systems, just like how he did in the first movie when transferring in a matter of seconds into Tony's suit. The incredible amount of data involved in his AI would need a lot of computing power and storage, plus a transfer of it I imagine would be time consuming. He would be the equivalent of an AI with a giant training model covering just about anything and an extremely complex layered neural net.
the more access to information the ai has, the smarter it can get. give it access to the entirety of the internet, including government confidential records and ai training, and it will be perfectly stand alone. add in the human "core" and the ai will actually have to hold back and adapt to what the human is capable of, as its primary weakness.
@@SimonBenjamin Yes. Actor Paul Bettany, who plays the voice of JARVIS or Vision, has a British accent and was born in Great Britain. I think a user interface of this complex type like JARVIS is a matter of the near future. :). I wish you good luck in your further work, Professor. I've always enjoyed your lessons: D
@@rudra8705 Hmm well I'm not sure how much information we have on it from the film. Do we know much beyond the fact that it is a compact thing with a ring like structure and wires wrapped like a "toroidal solenoid"? Difficult to tell what the physics could be just from that, although we can put limits on in like I did in this video.
I loved your take on Ironman. I really admire how he was a science based hero. I did a video reaction to the aerospace elements of this film. But I'm really glad to covered the arc reactor. That's definitely something I didn't want to get into. I'm more of an aero guy.
18:06 Distributed thrusters is actually a thing that Tony adds in his Mk-2 suit once he comes back home (probably because of the massive injury he faced after the crash landing of the crude Mk-1 suit). If you nitpick through the first montage of him training to use his new suit, you will see the initial pre-flight caliberation sequence that Jarvis runs during the suit up. Everytime Tony enters his flight mode or uses his palm thrusters for offensive blasts, the distributed thrusters in this back also light up and fire off for counterbalance. These tiny thrusters, accompanied by tiny moveable winglets, from my observation are present near his abdomen, higher back, middle back, thighs and leg calves which help him in his flight balance and save him from momentum impacts.
I have a two-year physics degree myself, and this is awesome. Iron Man is my favorite superhero. My favorite fictional character of all time is Doctor Doom.
Yeah iron man inspires us to think what we can do without superpowers! I don’t know so much about doc doom but he seems to have an interesting story as a leader
@@SimonBenjamin Except the Tony Stark's brilliant mind is a sort of superpower that along with his wealth allows him to create the powers of flight, super strength, durability, and various projectile and energy weapons that let him strike at a distance.
i guess Im randomly asking but does anybody know of a way to log back into an Instagram account..? I was stupid forgot the account password. I love any assistance you can offer me.
Just to clarify one thing. When Tony explained his reactor’s power it was the first one and in the movie he upgrades it and the bad guy stole the upgraded one and he had to use the old one that he made in the cave and the A.I said that one is not designed to fly. Also the tank hitting Tony it doesn’t show it was direct most likely it just grazed him and sent him off balance. Thanks for the math you doing amazing video by the way I love it.
Yep true we don’t know whether the tank shell was direct or glancing. However if you watch the scene the impact does dramatically change the way Tony is moving, so there is a big change in momentum, and his body would have to pay the price for that. And yep the power reactor gets better over the movie (and over following movies) I guess I’m saying that even the first one has plenty of power to make the things we see possible (from and energy point of view at least).
@@SimonBenjamin I would love a updated video on the suit. Since the tech he's using in the suit can be something like graphene or carbon nano tubes or artificial muscles that is either dampening the force that the armor pieces on he's suit experiences and counter reacts that down to the level that makes it equal to the damage he took as seen when he's home and out of the suit. And the suit has a pressurized internal area for him and he's body too. And the shell he got hit by can also just be a AA shell/shrapnel shell or a HE shell, since it's Shooting at a flying target witch would mean any sabo or anti armor rounds would be most likely not used for something like that at those ranges (1-2km by a estimation of the distance shown in the movie) and since he lands or crashes some hundred meters away from the tank it's self maybe as much as 500m but more likely around 100-200m out. The arc reactor on the other hand can be a more advanced version of the prototype large plasma/fusion reactors we are currently testing and building here in europe. And last but not least....he's weight....200kg is not that much for something that advanced....so i'd increase it to at least 400kg maybe even 500kg. Love the break down and how you have done the video.
Well, these kind of videos should definitely get more attention. From people with your educational level and your professional approach, it's just so good to watch. Plus, viewers learn something. The expression when you talk about Hulk is phenomenal. Nice!
I know this is four years old but seriously….I wish I had a teacher like you to help explain me abstract concepts like this. My problem was always visualizing it and that prohibited my relation and in turn my learning. If you I could have had someone like you teach me using comic books and movies….I have been such a better student. Good job dude and thank you for doing this. Also to kind of bring a bit of nerdiness into this: the movie does depict several additional thruster through out the suit for flight stabilization. If you review the scenes when he is developing flight in the suit you can see these several tiny thrusters in the exposed boot as he successfully lifts off. I do not know if they are enough thrusters or anything like that for what you said. But i believe we are left to assume there are several flight stabilizing thruster through out the suit. One could assume that power could be routed to those thrusters in a big way via automation in the form of the algorithms in the Jarvis AI. I dunno if I am on the right track or reaching. I am but a simple aircraft mechanic here lol but I would love to get your feedback….even though I am four years late to watching your video. Thank you again so much
Due to the demands of physics, it is no doubt better to fly an Iron Man suit using "CGI animation" instead an actor wearing a practical suit trying to fly it due to speeds and gravity. LOL. Thanks for explaining all the limitations of wearing an Iron Man suit. Great video!
Momentum conservation makes a perfect case for the infeasibility of such a suit today, at least one that can carry a human inside of it. Generating an artificial gravity field, one whose intensity and direction can be instantly controlled at will, might solve the problem, but this is definitely a project for the far future :) Thank you for the nice analysis!
@@manu144x I think the suit is still useful in that case actually. It would be much more clunky, and in a combat scenario, disadvantageous to you if the environment was modified to create that artificial gravity. Not to mention much more expensive. Whereas the suit as a localised environment will always have an actively modified gravity for the user only.
@@dunkeykung1162 If you can manipulate gravity just make a gravity field around you and any object thrown at you would just stop and ‘fall’ back. Or go around you. Also, any object can be weaponized. Maybe you’d need the suit so you have weapons onboard and look cool but beyond that not much :)
I actually really enjoyed this video, I love how you’re diving in to the physics and explaining the science behind the power that would be needed. The arc reactor, I think of it as a cold fusion, which of course is something that hasn’t been successfully achieved yet (to my knowledge) and then if we did get it started, how stable would it be. Great video
One possible explanation could be drawn from the comics. One of the armor's standard features is an EM force field. This is most likely what protects Tony from impact trauma, his suit generates an energy shield that reinforces its already impressive durability, while also protecting him from massive impacts that should liquefy him through sheer force. This would also explain why Rhodey was so badly injured from the type of fall that he and Tony have both most likely survived dozens of times over, his power source was destroyed, and his EM field with it.
12:10 It depends on what kind of projectile hits him and if it's hit as you have assumed wich is basicly worst case scenario or if it's glancing hit (bounce) wich can be anywhere from deadly to survivable. From the short clip shown in movie my best guess for shell type is some kind of HEAT shell wich uses explosives in the shell to get trough armor.
Love the explanation of conservation of momentum. I’ve seen other films overlook this fact as well. Bulletproof, even missile proof, doesn’t mean momentum proof!
Comments Correction: Many commenters argue the impact could be absorbed by ballistic gel, vibranium, or some other material to uniformly distribute the force across Tony's body. But this is confusing uniformly distributing loads with the conservation of momentum. At 14:02-15:00, Simon says he generously allows for the hands of god by saying Tony is accelerated over a distance of 1 meter. Tony's body wouldn't have to be broken by the suit - it would liquify itself internally (imagine a centrifuge separating the contents of liquids). Eg: If you were neutrally buoyant in an infinitely strong pool and it was dropped from a height of 1km, you would be perfectly enveloped by the water on impact (and would remain surrounded by water), but you would still be toast. For example, your lungs would be forced up relative to your denser parts being forced down within your body.
I was hoping you would also dive into the fact that that much energy, strapped to his chest, would also release enough heat to melt him down, before even putting on the MK1 suit.
@AmukelaniMaphumuloSIUU I saw that one, too, but I'm sure I got it from somewhere else before that, my head is an encyclopedia of useless facts, but, eventually, I have to keep the facts and forget the source... XD
May I Propose that the suit could have a gel layer to help absorb the impact and distribute it thru the suit? almost like what they would use in the Halo Franchise a Hydrostatic Gel Layer which is a semi-liquid substance conforming to the wearers body regulating temperature and has an ability to pressurize to help the survive hard impacts and landings not MCU Canon but none the less possible knowing tony's ways of adapting to circumstances possible future ones and past ones
This "gel layer" (which couldn't be more than 10cm) was more than accounted for when he said the acceleration takes place through the size of his body. The problem discussed isn't distributing the force, it is surviving the acceleration.
Would generating a magnetic field capable of exerting a magnetic force strong enough to decelerate the shell right before impact so that it doesn't hit him with such a high velocity work? Or would declerating the shell only cause Tony to accelerate in the opposite direction of the magnetic force thereby still leading to lethal acceleration?
BRILLIANTT, THANK YOU FOR MAKING THIS VIDEO PROFESSOR. I am a high school student from Indonesia and im really interested in physics. I wanna ask professor, is it possible to make a flying tech, imagine its like a long shoes that at the calves part i make a slim hole that fits aerodinamicly with my legs and works like a vacuum cleaner, sucking air in big mass and push the sucked air from my foot to act as a booster so that i can fly, and also make the same tech in my arms to control the direction when im flying. I cant stop thinking about this theory lately but i need a professional to guide me, i hope i will be as smart as you and you responded to this thoughts, thank you professor.
Hi, thanks for the comment. Well what you are describing is similar to the way regular jets work (which heat up air to make it expand and push it out the back) or drone engines (which are just fans to push the air) so it would definitely be possible according to physics! The challenge is to have a light and powerful source of energy to make it all work. The recent progress in drones is partly because of better batteries, but you'd need something even better to lift a human and keep them flying for a reasonable time.
what about heat distribution this is a big thing if it made thrust that can lift you in that kind of space there isn't a metal that can last very long without melting and fusing with your hands and feat
Note: I may be right I may be wrong. I think Tony has this into consideration as well. Further in the movie, when he comes back after killing the terrorists in the village, and pepper walks in and says "are those bullet holes" We are able to see inside of the suite for a moment. There's another piece of armour which is few cm in distance to the actual suite over his spandex suite that he was wearing all the time inside the Titanium alloy suite. So when there was a great impact on the outer suite by shell and then he dropped to ground using your explained physics, the momentum was conserved by the inner armour and not Tony's human body. Cannot say the same about his head though. Let me know if I got it or that would also fail.
@@gilcarvalho7744 Agree with you. "IMO" the internal armor is like an armor inside the armor to keep Tony safer than normal ( if not totally safe) and save him from getting splat pasted. Like that one stays suspended inside the Titanium alloy in case the outer armor actually rips apart like in Ironman 3. Not to sound too much taken about it (as it actually isn't physically real thing, yet.) but Marvel has showed each added feature clip in first three Iron man and Avengers movie. I think the suits went beyond physics after Ultron.
One issue with a generator producing 3GW of power right next to (or even in!) a man's chest that you didn't mention is the amount of heat it would be generating. Even if the Arc Reactor itself has perfect 100% efficiency, simply transporting that kind of energy via simple wires, or using it in thrusters, would most definitely produce a significant amount of heat. I'm sure Tony Stark would've thought about some sort of cooling system, but I do wonder if the limits of physics would let that be enough.
@@mrmogelost6720 In the movies at least it is described as cold fusion. IDK how one would make and contain a black hole in a cave with spare missile parts. Not to mention the black holes are so massive it's hard to comprehend, and grow in mass as they "operate". No way Tony would've been able to carry that in his chest.
The arc reactor is a miniaturized fusion reactor and it seems to have limitless fuel because what it does is pull ambient hydrogen out of the local atmosphere
As far as I know, it’s a made up thing at any scale. But it definitely sounds like a real thing so good job to the writers! I suppose in the movie it was a real thing before Tony got captured and then he miniaturised it - but in real life it isn’t a thing at all. Maybe you need to invent it :)
im so glad you brought up the momentum problem, i was about to ask that in the comments but then ive watched the whole thing and the last half of the video is all about it lol
Can't he just have shock absorbers in his suit so that he is safe from all the deadly forces and also be safe by absorbing the forces and spreading them throughout his outer layer of the suit thus balancing the law of conservation of momentum ????
You may be confusing point load distribution with overall acceleration (conservation if momentum). The "absorption" was accounted for when he said that the acceleration occurs through the size of his body.
On his propulsion systems, from what I know tony stark uses muons as his propulsion method and main weapon systems in his palms, would this be possible.
hmm I don't see why not! Muons are made naturally in the upper atmosphere from high energy light striking atoms in the air, so Tony's suit could create them too as long as the suit has enough energy (which it can have plenty of, as I work out in the video). of course he would need to create much more intense muon radiation than the natural level. Muons also penetrate further into matter than (say) x-rays so it might make a dangerous weapon.
Great video, I really loved it. In the comics at least, Tony had come up with a neat way to bypass the problems of acceleration of the suit on the human body internally of flight forces g's, and also externally from incoming objects, i.e the tank shell, or whatever else, via his Tony Stark patented "inertial dampening field" (exactly like you mentioned for the STTNG). So that IDF would minimize or cancel out incoming tank shells, suddenly massive momentum acceleration/deceleration launching into flight/landing or slamming into the ground as he did. Tony Stark as a mega-super genius did come up with the inertial dampening field, his mini-ARC reactor, his very intelligent general AI JARVIS,, and even more. I would think the one thing that he couldn't do, would be to create a near 100% efficient power reactor to generate 3 GJ/s / 3 MW of power from something that tiny, Without it creating either a huge amount of heat or radiation as well as by-products of its power generation, so cooking him inside the suit by that alone, or irradiating his body in the course of the power generation. Tony did come up with a Structural Integrity Field (SIF) to reinforce his armor from penetrating hits from incoming high-velocity rounds, armor-piercing around, etc. and thereby making his armor pretty much nigh-impregnable except by extremely powerful impact forces to over-power the suit defenses, and magic of course.
Ah that’s interesting, I’m glad that the writers thought about the problem and made it so that Tony has solved it. I think it’s really, really hard to solve though - probably a problem for hundreds of years in the future, rather than a really smart guy in the current era. For a power source that doesn’t get hot... that’s more of a huge engineering challenge than a problem with basic physics. In principle you can add a heat pump (powered by a fraction of the reactor’s output) that takes waste heat to anywhere you want it e.g. the flight boosters. Mind you, practically all today’s power systems DO use ‘thermal reservoirs’ to just dump heat, and Tony can’t do that, so a lot of the innovation in the suit would need to go into this issue.
Moscovium plates distributed over the surface of his suit. Perfect fix. Moscovium(element 115) is postulated to generate gravity. The plate configuration could be such to generate a gravity well around his body enabling it to withstand or nullify inertial forces. Of course, he would've discovered the means to stabilize that ephemeral element.
I guess using Tony starks nanotechnology the nanomaterials making up his suit cud be propelled with a significant enough acceleration to oppose the launcher. So long as they were propelled at a big enough distance from Tony (but small enough to reassemble on his body) the force cud propel them again back into Tony's suit. Assuming there is sufficient absorbant padding under his suit his body cud survive a blast like that as his body now needs to accelerate less to survive.
Yeah I think that the cool nanotechnology suit in the Infinity Gauntlet movies could potentially solve the problem. Because that thing is so advanced that we can’t say what it can/can’t do - maybe the nano-elements of the suit can produce a counter-force when needed as you say. That’s why I focused on the suits from the first movie since they seem limited to near-future technology
Bit late, bud to be fair, their universe has actual gods, magic stones, a big, green man who didn't die, and a girl who can travel the multiverse without even knowing how. I think it's fair to say they might have different g forces than us🤷🏼♂️ But it's a GREAT video for a similar device created in our universe.
Hmm well I’d like to do one on a different hero first. I was thinking of the hulk but perhaps I’ll do one when another cool Marvel movie comes out, about whichever hero is in the movie. Spiderman maybe eh?
This is such a great explanation, as to what I thought each time Tony Stark came in contact with a projectile... I don't know the exact math, but given the magnitude of the impact (inertia) from him falling out of the sky, would have definitely killed him or caused some very serious damage to his body. That's exactly why I never continued building the Iron Man suit, only the A.I.
To my knowledge, what would have killed him long before the massive acceleration is the efficiency. Even if we say that efficiency of that power generator is 99,9%, given that it produces 3GJ/s it would bake him in an instant. Not to say that efficiency of units in his suit (jet engines and others) are nowhere near 99,9%
@@digitalcurrents but what happens to that energy? We know energy cannot be destroyed and black holes evaporates, so they will return exactly the amount of energy they consumed. In a closed system energy must be conserved
10:24 I would like to point out that that number is the total energy consumed over the distance. And that’s a fraction of what the reactor produces in a second. So basically, with these assumptions, the suit could fly 10km in under a second (starting with 0m/s)
I wanted to check something which went unmentioned - namely, how much heat is Tony producing with his thrusters? When Iron Man goes 10 km straight up, 20 megajoules of his power goes into thrust. However, because his thrusters are only 10% efficient, they consume 200 megajoules to do it That extra 180 megajoules goes at least partly into light and sound, but mostly heat. How much? I did the calculation for titanium, and it's enough heat energy to raise the temperature of 100 kg of titanium by about 2500 degrees Celsius (unless I'm embarrassing myself with bad math). Obviously, that heat would be almost entirely dispersed away from Tony's body; it's not like he points the thrusters towards himself! But that's still a very significant amount of heat coming out of those thrusters, enough so that whatever takes off from or lands on had better not be something he wants to keep. Also, one really can't blame the robot for repeatedly dousing him with a fire extinguisher. However, I think that the manner in which the thrusters are shown on screen indicates that they are actually much more efficient than that. When he blasts things with them, they get thrown across the room; they don't tend to scorch and burn. So, somehow, a much greater percentage of the energy generated by his suit goes into actual thrust rather than heat. The question of how efficient a thruster can be within the laws of physics, I leave to Mr. Benjamin. Thanks for the entertaining and thought-provoking video!
judging by the design of the big arc reactor its seems to actually be a Hadron Collider just smaller like the ones that are apparently being made today (more close to the size of the big one that Howard Stark made not smaller ones as in the one Tony made) and there might be a way to shrink it even more than we currently are although the heat would likely burn Tony to a crisp
I think many of us already knew, surviving the kind of impacts shown in the movies, is the *unrealistic portion... But this is a great video! Congratulations *Unrealistic meaning it defies the laws of physics not that it goes beyond present technology.
Yeah depending on the movie (or comic) you read, vibranium definitely seems to be able to violate momentum conservation. To a physicist this is may actually be a bigger deal than, say, time travel ;)
I’m sure it’s been mentioned but we actually see most of Tony’s suits have additional thrusters in the shoulder blade and calf areas. The portrayal of these features varies between movies but it is in fact there. Also I would imagine as the genius defense contractor & weapons designer he is, he would make sure Jarvis is constantly on alert for nearly imperceptible threats to auto engage before Tony could even react or simply without His input. I mean we now have pretty decently self driving cars, albeit with room for improvement, they can parallel park, tell if somethings in their path, stop or attempt to avoid collisions, and maneuver down a highway pretty easily… so it’s probably safe to say tony incorporated micro thrusters akin to those on satellites or large sea vessels to maintain stability or do fine course corrections. Regardless great insights here, I’ve seen this vid a couple times over the years and it’s always a joy!! Thanks dude!
I really like this video, I am not the smartest person. I am not even a great mathematician, however the in depth descriptions and simplified explanations really helped me to understand what was being spoken about. I greatly appreciate that. I love watching videos like this, but unfortunately I don't know any who do it as well, or with such great exuberance.
17:08 *I was thinking that it's the inertia that would kill him by maybe smashing his brain against his skull rather than the suit squashing him in because of the material science involved.* I don't know exactly what the suit is made of but I think I've heard somewhere that some of them are made of Vibranium and Adamantium. Those metals are too durable to bend under the pressure of the tank shell. If the suit is made of Vibranium, then it could absorb some of the vibrations and increase his chances of surviving the hit. I think that Inertia smashing his insides is the more bigger problem rather than the structural integrity of the suit caving in under the pressure.
In the movie it's actually stated that the suit is made out of a gold-titanium aloy, however it's very likely that Tony added a layer of some tough material either under or on top of the outer layer of the suit.
ok so here is your second question answer.... look first admit that tony suit is made up of super light and strongest material secondly, if a 5kg missile go through his suit then it pushes THE SUIT from one to another direction because of momentum.. and his suit will absorb all momentum.... so inside today will only travel with it because of the toughness of the suit...
For the shell example, you are assuming that he stops the shell, but, you can see in the video, that it makes him "spin" and therefore the motion deflects some of the impact?
With MCU Iron Man having his suit being made of a Gold Titanium alloy from metallic bonding aka infusion, flying with such ease and reaching supersonic speeds past Mach 1, would having such alloy be possible for sustained flight along with all the other key points that you mentioned?
It have to have ridiculous amount of power to have sustained flight with out wings. There are jet cars that get the same turbines that were put in fighter jets but they don’t fly.
Wow I love this video exactly my thoughts, a gravity like force that acts on every molecule on his body to completely avoid internal forces. That is soo cool
Thinking about power source, antimatter seams best. What's more, you can use it for defense system by shooting it from suit, to destroy anything that was thrown at you. Something similiar as we could see in "expansion", where they use guns as some sort of shield against incoming objects. Of course you would have to prevent antimatter from touching regular matter by using strong magnetic field. While shooting such antimatter projectile you would have to have it trapped in some form of cage (clathrate maybe?) while traveling through air. Antimatter seams a good source of propulsion too, while you don't have to produce all the energy you need inside you suit (whereas you produce less heat), you can just use it as rocket engine
The math you were doing for the 3MJ/second would be for the FIRST ARC reactor. As you remember, when Tony has to use the old reactor at the end of the movie, Jarvis said the reactor wasn't set for continuous flight. So the new ARC reactor was producing MORE power than the first one.
This is the first video I'm watching in your channel, and this video really excites me since I'm looking forward to taking physics class next year in high school! Thank you for making this video so interesting and helpful.
quick question, even if the small generator didnt produce that much power couldnt you install a small alternator inside the suit to keep it working and charged like you do with a car?
high quality shock absorbers under every piece of the armor, fitted interior with little to no wiggle room, made with a cushiony inner layer like memory foam, and locking joints, protecting against dangerous contortions.
My understanding of the momentum issue was that the forces are distributed uniformly through his body by diamagnetic repulsion, similar to the levitating frog demo, but scaled up.

Tony somehow tanking all the g-forces he’s subjected too throughout the mcu is the hard pill to swallow for me.
As soon as his suit opens, a puddle of meat should just flop out
Just to clarify one thing. When Tony explained his reactor’s power it was the first one and in the movie he upgrades it and the bad guy stole the upgraded one and he had to use the old one that he made in the cave and the A.I said that one is not designed to fly.
Also the tank hitting Tony it doesn’t show it was direct most likely it just grazed him and sent him off balance.
Thanks for the math you doing amazing video by the way I love it.
Yep true we don’t know whether the tank shell was direct or glancing. However if you watch the scene the impact does dramatically change the way Tony is moving, so there is a big change in momentum, and his body would have to pay the price for that.
And yep the power reactor gets better over the movie (and over following movies) I guess I’m saying that even the first one has plenty of power to make the things we see possible (from and energy point of view at least).
Simon Benjamin thank you for explaining everything man appreciate that.
@@SimonBenjamin You are dangerously right!
didnt expect luffy to say something so smart
@@SimonBenjamin I would love a updated video on the suit.
Since the tech he's using in the suit can be something like graphene or carbon nano tubes or artificial muscles that is either dampening the force that the armor pieces on he's suit experiences and counter reacts that down to the level that makes it equal to the damage he took as seen when he's home and out of the suit.
And the suit has a pressurized internal area for him and he's body too.
And the shell he got hit by can also just be a AA shell/shrapnel shell or a HE shell, since it's Shooting at a flying target witch would mean any sabo or anti armor rounds would be most likely not used for something like that at those ranges (1-2km by a estimation of the distance shown in the movie) and since he lands or crashes some hundred meters away from the tank it's self maybe as much as 500m but more likely around 100-200m out.
The arc reactor on the other hand can be a more advanced version of the prototype large plasma/fusion reactors we are currently testing and building here in europe.
And last but not least....he's weight....200kg is not that much for something that advanced....so i'd increase it to at least 400kg maybe even 500kg.
Love the break down and how you have done the video.
Well, these kind of videos should definitely get more attention. From people with your educational level and your professional approach, it's just so good to watch. Plus, viewers learn something. The expression when you talk about Hulk is phenomenal. Nice!
I like that you took the very optimistic and enthusiastic approach to the physics of Iron man.
I know this is four years old but seriously….I wish I had a teacher like you to help explain me abstract concepts like this. My problem was always visualizing it and that prohibited my relation and in turn my learning. If you I could have had someone like you teach me using comic books and movies….I have been such a better student. Good job dude and thank you for doing this.
Also to kind of bring a bit of nerdiness into this: the movie does depict several additional thruster through out the suit for flight stabilization. If you review the scenes when he is developing flight in the suit you can see these several tiny thrusters in the exposed boot as he successfully lifts off. I do not know if they are enough thrusters or anything like that for what you said. But i believe we are left to assume there are several flight stabilizing thruster through out the suit. One could assume that power could be routed to those thrusters in a big way via automation in the form of the algorithms in the Jarvis AI. I dunno if I am on the right track or reaching. I am but a simple aircraft mechanic here lol but I would love to get your feedback….even though I am four years late to watching your video.
Thank you again so much
Due to the demands of physics, it is no doubt better to fly an Iron Man suit using "CGI animation" instead an actor wearing a practical suit trying to fly it due to speeds and gravity. LOL. Thanks for explaining all the limitations of wearing an Iron Man suit. Great video!
Momentum conservation makes a perfect case for the infeasibility of such a suit today, at least one that can carry a human inside of it. Generating an artificial gravity field, one whose intensity and direction can be instantly controlled at will, might solve the problem, but this is definitely a project for the far future :)
Thank you for the nice analysis!
The irony is that If you have the capability to manipulate gravity, you don't need such a suit, it would be useless.
@@manu144x I think the suit is still useful in that case actually. It would be much more clunky, and in a combat scenario, disadvantageous to you if the environment was modified to create that artificial gravity. Not to mention much more expensive. Whereas the suit as a localised environment will always have an actively modified gravity for the user only.
Joe Rogan joined the chat
Wouldn't reactive armor from a Modern tank - if it covered his suit - negate much of the momentum of the incoming penetrating shell?
@@dunkeykung1162 If you can manipulate gravity just make a gravity field around you and any object thrown at you would just stop and ‘fall’ back. Or go around you. Also, any object can be weaponized.
Maybe you’d need the suit so you have weapons onboard and look cool but beyond that not much :)
guys that is why its call a MOVIE. and a great one too... just sit back and enjoy it dhaaa.
I actually really enjoyed this video, I love how you’re diving in to the physics and explaining the science behind the power that would be needed. The arc reactor, I think of it as a cold fusion, which of course is something that hasn’t been successfully achieved yet (to my knowledge) and then if we did get it started, how stable would it be. Great video
One possible explanation could be drawn from the comics. One of the armor's standard features is an EM force field. This is most likely what protects Tony from impact trauma, his suit generates an energy shield that reinforces its already impressive durability, while also protecting him from massive impacts that should liquefy him through sheer force. This would also explain why Rhodey was so badly injured from the type of fall that he and Tony have both most likely survived dozens of times over, his power source was destroyed, and his EM field with it.
12:10
It depends on what kind of projectile hits him and if it's hit as you have assumed wich is basicly worst case scenario or if it's glancing hit (bounce) wich can be anywhere from deadly to survivable.
From the short clip shown in movie my best guess for shell type is some kind of HEAT shell wich uses explosives in the shell to get trough armor.
Ok
Love the explanation of conservation of momentum. I’ve seen other films overlook this fact as well. Bulletproof, even missile proof, doesn’t mean momentum proof!
Hello
This video was a 3 in 1
science
english (i'm french)
and superhero story
I've learned so much in 1 video... Thanks alot !
Glad you enjoyed it Milo!
Comments Correction:
Many commenters argue the impact could be absorbed by ballistic gel, vibranium, or some other material to uniformly distribute the force across Tony's body. But this is confusing uniformly distributing loads with the conservation of momentum.
At 14:02-15:00, Simon says he generously allows for the hands of god by saying Tony is accelerated over a distance of 1 meter. Tony's body wouldn't have to be broken by the suit - it would liquify itself internally (imagine a centrifuge separating the contents of liquids).
Eg: If you were neutrally buoyant in an infinitely strong pool and it was dropped from a height of 1km, you would be perfectly enveloped by the water on impact (and would remain surrounded by water), but you would still be toast. For example, your lungs would be forced up relative to your denser parts being forced down within your body.
Love this video so much! I inspire to be an engineer and physicist one day, so the more the knowledge I learn the better! keep up the content!
I was hoping you would also dive into the fact that that much energy, strapped to his chest, would also release enough heat to melt him down, before even putting on the MK1 suit.
That is true I heard that from Dr Neil on a short😅
@AmukelaniMaphumuloSIUU I saw that one, too, but I'm sure I got it from somewhere else before that, my head is an encyclopedia of useless facts, but, eventually, I have to keep the facts and forget the source... XD
May I Propose that the suit could have a gel layer to help absorb the impact and distribute it thru the suit? almost like what they would use in the Halo Franchise a Hydrostatic Gel Layer which is a semi-liquid substance conforming to the wearers body regulating temperature and has an ability to pressurize to help the survive hard impacts and landings not MCU Canon but none the less possible knowing tony's ways of adapting to circumstances possible future ones and past ones
This "gel layer" (which couldn't be more than 10cm) was more than accounted for when he said the acceleration takes place through the size of his body. The problem discussed isn't distributing the force, it is surviving the acceleration.
You still run into the issue of your internal organs liquifying inside your body.
You should talk more about those kind of super hero science stuff, I Just can't get enough of It!
Become a very big fan of yours from last some days.I like the way you are explaining the physics behind IronMan armor(India).
Glad to hear you enjoyed it Nisha!
Sir my name is Tanish. Nisha is my aunt's name.
Would generating a magnetic field capable of exerting a magnetic force strong enough to decelerate the shell right before impact so that it doesn't hit him with such a high velocity work? Or would declerating the shell only cause Tony to accelerate in the opposite direction of the magnetic force thereby still leading to lethal acceleration?
BRILLIANTT, THANK YOU FOR MAKING THIS VIDEO PROFESSOR.
I am a high school student from Indonesia and im really interested in physics. I wanna ask professor, is it possible to make a flying tech, imagine its like a long shoes that at the calves part i make a slim hole that fits aerodinamicly with my legs and works like a vacuum cleaner, sucking air in big mass and push the sucked air from my foot to act as a booster so that i can fly, and also make the same tech in my arms to control the direction when im flying. I cant stop thinking about this theory lately but i need a professional to guide me, i hope i will be as smart as you and you responded to this thoughts, thank you professor.
Hi, thanks for the comment. Well what you are describing is similar to the way regular jets work (which heat up air to make it expand and push it out the back) or drone engines (which are just fans to push the air) so it would definitely be possible according to physics! The challenge is to have a light and powerful source of energy to make it all work. The recent progress in drones is partly because of better batteries, but you'd need something even better to lift a human and keep them flying for a reasonable time.
You should try putting that device on your Center of mass so yo can probably fly or hover without falling becouse of your legs balance
@@SimonBenjamin what if we use the air as source of energy.Like as it can be used to make renewable energy..
Hey i am actually interested in ur idea
I am ready to make this true
I too wanna make this dream come true
Let's make a real suite
what about heat distribution this is a big thing if it made thrust that can lift you in that kind of space there isn't a metal that can last very long without melting and fusing with your hands and feat
cold fusion is what its more similar to just that no major strides have been done with it in decades.
Great job professor but where’s physics in incredible Hulk video? ;)
In my head until I can find time for it :D
🤣🤣🤣
I enjoyed this video
Thanks for making this video
Note: I may be right I may be wrong.
I think Tony has this into consideration as well. Further in the movie, when he comes back after killing the terrorists in the village, and pepper walks in and says "are those bullet holes" We are able to see inside of the suite for a moment. There's another piece of armour which is few cm in distance to the actual suite over his spandex suite that he was wearing all the time inside the Titanium alloy suite.
So when there was a great impact on the outer suite by shell and then he dropped to ground using your explained physics, the momentum was conserved by the inner armour and not Tony's human body. Cannot say the same about his head though.
Let me know if I got it or that would also fail.
it's not enough space to decelerate, still tony paste all over
@@gilcarvalho7744 Agree with you. "IMO" the internal armor is like an armor inside the armor to keep Tony safer than normal ( if not totally safe) and save him from getting splat pasted. Like that one stays suspended inside the Titanium alloy in case the outer armor actually rips apart like in Ironman 3.
Not to sound too much taken about it (as it actually isn't physically real thing, yet.) but Marvel has showed each added feature clip in first three Iron man and Avengers movie.
I think the suits went beyond physics after Ultron.
The inside is all the framing for the circuitry.
Nono it went beyond in the first one. There’s no power source that could operate it without just cooking someone.
i like your explanation sir.
One issue with a generator producing 3GW of power right next to (or even in!) a man's chest that you didn't mention is the amount of heat it would be generating. Even if the Arc Reactor itself has perfect 100% efficiency, simply transporting that kind of energy via simple wires, or using it in thrusters, would most definitely produce a significant amount of heat. I'm sure Tony Stark would've thought about some sort of cooling system, but I do wonder if the limits of physics would let that be enough.
Superconducting wires?
What if the Iron Man arc reactor has a self-contained mini-black hole? What if the reactor redirects the heat into the black hole?
@@digitalcurrents But that's Star Trek tech
@@mrmogelost6720 In the movies at least it is described as cold fusion.
IDK how one would make and contain a black hole in a cave with spare missile parts.
Not to mention the black holes are so massive it's hard to comprehend, and grow in mass as they "operate". No way Tony would've been able to carry that in his chest.
Was thinking that sa well.
You are a hero and you cleared off my all the doubts about Tony's suit
And Thank you for this wonderful video.
And plz keep making videos like this.
The arc reactor is a miniaturized fusion reactor and it seems to have limitless fuel because what it does is pull ambient hydrogen out of the local atmosphere
It would cook him inside the suit.
I Love when you say "pasted" lol
I thought the Arc Reactor is real but it’s just not miniaturized.
As far as I know, it’s a made up thing at any scale. But it definitely sounds like a real thing so good job to the writers! I suppose in the movie it was a real thing before Tony got captured and then he miniaturised it - but in real life it isn’t a thing at all. Maybe you need to invent it :)
In some of the later fiims, Tony also have these thrusters to potentially cancel the momentum
im so glad you brought up the momentum problem, i was about to ask that in the comments but then ive watched the whole thing and the last half of the video is all about it lol
Yep it's the key thing... and true of so much superhero stuff when you think about it
I can't believe UA-cam brought this to me after 4yrs, this video is amazing ❤️❤️
Can't he just have shock absorbers in his suit so that he is safe from all the deadly forces and also be safe by absorbing the forces and spreading them throughout his outer layer of the suit thus balancing the law of conservation of momentum ????
You may be confusing point load distribution with overall acceleration (conservation if momentum). The "absorption" was accounted for when he said that the acceleration occurs through the size of his body.
Love the description of forces as being communicated too
On his propulsion systems, from what I know tony stark uses muons as his propulsion method and main weapon systems in his palms, would this be possible.
hmm I don't see why not! Muons are made naturally in the upper atmosphere from high energy light striking atoms in the air, so Tony's suit could create them too as long as the suit has enough energy (which it can have plenty of, as I work out in the video). of course he would need to create much more intense muon radiation than the natural level. Muons also penetrate further into matter than (say) x-rays so it might make a dangerous weapon.
Simon Benjamin and would there increase mass compared to electrons explain the weapons damage
@14:25 The super hero/ villain pose of triumph and excitement with fists clenched. haha. awesome. "14 zeros... ( The pooower!!! muhahaha!)"
Great video, I really loved it. In the comics at least, Tony had come up with a neat way to bypass the problems of acceleration of the suit on the human body internally of flight forces g's, and also externally from incoming objects, i.e the tank shell, or whatever else, via his Tony Stark patented "inertial dampening field" (exactly like you mentioned for the STTNG). So that IDF would minimize or cancel out incoming tank shells, suddenly massive momentum acceleration/deceleration launching into flight/landing or slamming into the ground as he did. Tony Stark as a mega-super genius did come up with the inertial dampening field, his mini-ARC reactor, his very intelligent general AI JARVIS,, and even more. I would think the one thing that he couldn't do, would be to create a near 100% efficient power reactor to generate 3 GJ/s / 3 MW of power from something that tiny, Without it creating either a huge amount of heat or radiation as well as by-products of its power generation, so cooking him inside the suit by that alone, or irradiating his body in the course of the power generation. Tony did come up with a Structural Integrity Field (SIF) to reinforce his armor from penetrating hits from incoming high-velocity rounds, armor-piercing around, etc. and thereby making his armor pretty much nigh-impregnable except by extremely powerful impact forces to over-power the suit defenses, and magic of course.
Ah that’s interesting, I’m glad that the writers thought about the problem and made it so that Tony has solved it. I think it’s really, really hard to solve though - probably a problem for hundreds of years in the future, rather than a really smart guy in the current era.
For a power source that doesn’t get hot... that’s more of a huge engineering challenge than a problem with basic physics. In principle you can add a heat pump (powered by a fraction of the reactor’s output) that takes waste heat to anywhere you want it e.g. the flight boosters. Mind you, practically all today’s power systems DO use ‘thermal reservoirs’ to just dump heat, and Tony can’t do that, so a lot of the innovation in the suit would need to go into this issue.
I’d you have that then what’s the point of the full suit? To show off?
@@SimonBenjamin
Tony is portrait as that smart, he can even invent time travel in some weeks!
Moscovium plates distributed over the surface of his suit. Perfect fix. Moscovium(element 115) is postulated to generate gravity. The plate configuration could be such to generate a gravity well around his body enabling it to withstand or nullify inertial forces. Of course, he would've discovered the means to stabilize that ephemeral element.
I guess using Tony starks nanotechnology the nanomaterials making up his suit cud be propelled with a significant enough acceleration to oppose the launcher. So long as they were propelled at a big enough distance from Tony (but small enough to reassemble on his body) the force cud propel them again back into Tony's suit. Assuming there is sufficient absorbant padding under his suit his body cud survive a blast like that as his body now needs to accelerate less to survive.
Yeah I think that the cool nanotechnology suit in the Infinity Gauntlet movies could potentially solve the problem. Because that thing is so advanced that we can’t say what it can/can’t do - maybe the nano-elements of the suit can produce a counter-force when needed as you say. That’s why I focused on the suits from the first movie since they seem limited to near-future technology
Bit late, bud to be fair, their universe has actual gods, magic stones, a big, green man who didn't die, and a girl who can travel the multiverse without even knowing how. I think it's fair to say they might have different g forces than us🤷🏼♂️ But it's a GREAT video for a similar device created in our universe.
Can you make more videos on Iron Man plEase?
Hmm well I’d like to do one on a different hero first. I was thinking of the hulk but perhaps I’ll do one when another cool Marvel movie comes out, about whichever hero is in the movie. Spiderman maybe eh?
This is such a great explanation, as to what I thought each time Tony Stark came in contact with a projectile... I don't know the exact math, but given the magnitude of the impact (inertia) from him falling out of the sky, would have definitely killed him or caused some very serious damage to his body. That's exactly why I never continued building the Iron Man suit, only the A.I.
Awesome video sir, This channel is so underrated, your content is awesome, thank you professor
To my knowledge, what would have killed him long before the massive acceleration is the efficiency. Even if we say that efficiency of that power generator is 99,9%, given that it produces 3GJ/s it would bake him in an instant. Not to say that efficiency of units in his suit (jet engines and others) are nowhere near 99,9%
I dont't want the heat loss of 0.1% from 3GJ anywhere near my chest! lol!
Suppose the arc reactor is able to create self-contained quantum black holes and waste heat is redirected to these black holes?
@@digitalcurrents but what happens to that energy? We know energy cannot be destroyed and black holes evaporates, so they will return exactly the amount of energy they consumed. In a closed system energy must be conserved
10:24 I would like to point out that that number is the total energy consumed over the distance.
And that’s a fraction of what the reactor produces in a second. So basically, with these assumptions, the suit could fly 10km in under a second (starting with 0m/s)
I wanted to check something which went unmentioned - namely, how much heat is Tony producing with his thrusters?
When Iron Man goes 10 km straight up, 20 megajoules of his power goes into thrust. However, because his thrusters are only 10% efficient, they consume 200 megajoules to do it That extra 180 megajoules goes at least partly into light and sound, but mostly heat. How much? I did the calculation for titanium, and it's enough heat energy to raise the temperature of 100 kg of titanium by about 2500 degrees Celsius (unless I'm embarrassing myself with bad math).
Obviously, that heat would be almost entirely dispersed away from Tony's body; it's not like he points the thrusters towards himself! But that's still a very significant amount of heat coming out of those thrusters, enough so that whatever takes off from or lands on had better not be something he wants to keep. Also, one really can't blame the robot for repeatedly dousing him with a fire extinguisher.
However, I think that the manner in which the thrusters are shown on screen indicates that they are actually much more efficient than that. When he blasts things with them, they get thrown across the room; they don't tend to scorch and burn. So, somehow, a much greater percentage of the energy generated by his suit goes into actual thrust rather than heat. The question of how efficient a thruster can be within the laws of physics, I leave to Mr. Benjamin.
Thanks for the entertaining and thought-provoking video!
dude, you sound so excited about it. you must be an awsome teacher.
judging by the design of the big arc reactor its seems to actually be a Hadron Collider just smaller like the ones that are apparently being made today (more close to the size of the big one that Howard Stark made not smaller ones as in the one Tony made) and there might be a way to shrink it even more than we currently are although the heat would likely burn Tony to a crisp
Redirect the heat into a contained quantum black hole.
I think many of us already knew, surviving the kind of impacts shown in the movies, is the *unrealistic portion... But this is a great video! Congratulations
*Unrealistic meaning it defies the laws of physics not that it goes beyond present technology.
Oooooooor his suit should be of vibranium :D
Yeah depending on the movie (or comic) you read, vibranium definitely seems to be able to violate momentum conservation. To a physicist this is may actually be a bigger deal than, say, time travel ;)
thank you for making a video about almost every IM physics argument I've had since 2008
This video, is to much thinking for the average person.
the tank shell didnt hit him directly so the force calculation is off but crashing that fast would still kill him.
its more of a deflected hit not head on.
I loved how you explained everything
Is it possible to use ion thrusters, if we have better tech for ion thrusters then we can use electricity to fly.
this is better than most 10-50k subbed channels you desrve more views and subs this was great! you got a like from me
I’m sure it’s been mentioned but we actually see most of Tony’s suits have additional thrusters in the shoulder blade and calf areas. The portrayal of these features varies between movies but it is in fact there. Also I would imagine as the genius defense contractor & weapons designer he is, he would make sure Jarvis is constantly on alert for nearly imperceptible threats to auto engage before Tony could even react or simply without His input. I mean we now have pretty decently self driving cars, albeit with room for improvement, they can parallel park, tell if somethings in their path, stop or attempt to avoid collisions, and maneuver down a highway pretty easily… so it’s probably safe to say tony incorporated micro thrusters akin to those on satellites or large sea vessels to maintain stability or do fine course corrections.
Regardless great insights here, I’ve seen this vid a couple times over the years and it’s always a joy!! Thanks dude!
I really like this video, I am not the smartest person. I am not even a great mathematician, however the in depth descriptions and simplified explanations really helped me to understand what was being spoken about. I greatly appreciate that. I love watching videos like this, but unfortunately I don't know any who do it as well, or with such great exuberance.
18:12 so basically we need a high precision/efficient sensor and thruster so that it can act instantaneously when any potential stimulus hits 🎯
At 8:15, are you indicating that the ARC Reactor powered suit would last "(over 9 hours)" as in seconds, minutes or days longer?
17:08
*I was thinking that it's the inertia that would kill him by maybe smashing his brain against his skull rather than the suit squashing him in because of the material science involved.*
I don't know exactly what the suit is made of but I think I've heard somewhere that some of them are made of Vibranium and Adamantium. Those metals are too durable to bend under the pressure of the tank shell.
If the suit is made of Vibranium, then it could absorb some of the vibrations and increase his chances of surviving the hit.
I think that Inertia smashing his insides is the more bigger problem rather than the structural integrity of the suit caving in under the pressure.
In the movie it's actually stated that the suit is made out of a gold-titanium aloy, however it's very likely that Tony added a layer of some tough material either under or on top of the outer layer of the suit.
What if the shell just glanced off him and wasn't a direct hit, or what if the shell exploded on impact
This video is gonna blow up, keep up the good work!
ok so here is your second question answer....
look first admit that tony suit is made up of super light and strongest material
secondly, if a 5kg missile go through his suit then it pushes THE SUIT from one to another direction because of momentum.. and his suit will absorb all momentum....
so inside today will only travel with it because of the toughness of the suit...
He somewhat solved the momentum issue on his MK-42. You are great in your work.
For the shell example, you are assuming that he stops the shell, but, you can see in the video, that it makes him "spin" and therefore the motion deflects some of the impact?
Sounds like a concussion. Good point about the suit. He's taken so many hits. Can't wait to watch the movie with physics in mind.
Excellent work, let's build an iron man suit, iron man is my inspiration..
Marvel studios might have seen your video..
Iron man got back thrusters in infinity war😂
With MCU Iron Man having his suit being made of a Gold Titanium alloy from metallic bonding aka infusion, flying with such ease and reaching supersonic speeds past Mach 1, would having such alloy be possible for sustained flight along with all the other key points that you mentioned?
It have to have ridiculous amount of power to have sustained flight with out wings. There are jet cars that get the same turbines that were put in fighter jets but they don’t fly.
Really enjoyed your explanation of the types of forces on the suit. Ive always questioned that to myself.....lol. but job well done.
love every bit of this! fantastic
really like your approach to analyzing the physics.
New note: adding pillows to the suit
memory foam will be better and easier to use.
Please make more videos you're channel is really good
Thanks! I’d like to... anything in particular you’d like to see?
Really great explanation!
Wow I love this video exactly my thoughts, a gravity like force that acts on every molecule on his body to completely avoid internal forces. That is soo cool
Thinking about power source, antimatter seams best. What's more, you can use it for defense system by shooting it from suit, to destroy anything that was thrown at you. Something similiar as we could see in "expansion", where they use guns as some sort of shield against incoming objects. Of course you would have to prevent antimatter from touching regular matter by using strong magnetic field. While shooting such antimatter projectile you would have to have it trapped in some form of cage (clathrate maybe?) while traveling through air. Antimatter seams a good source of propulsion too, while you don't have to produce all the energy you need inside you suit (whereas you produce less heat), you can just use it as rocket engine
love the way you transmit you passion to physics. I'd love to assits to your classes, sincerely.
Could it be a some kind of mini hydraulic system in his armor that absorbs any impact?
The math you were doing for the 3MJ/second would be for the FIRST ARC reactor.
As you remember, when Tony has to use the old reactor at the end of the movie, Jarvis said the reactor wasn't set for continuous flight.
So the new ARC reactor was producing MORE power than the first one.
This is the first video I'm watching in your channel, and this video really excites me since I'm looking forward to taking physics class next year in high school! Thank you for making this video so interesting and helpful.
how is he flying sir like for flying wouldnt he be needing fuel for the thrusters..??
11:33 I guessed it right, the transfer of momentum from the attacker to Tony must fly him away 😂
quick question, even if the small generator didnt produce that much power couldnt you install a small alternator inside the suit to keep it working and charged like you do with a car?
high quality shock absorbers under every piece of the armor, fitted interior with little to no wiggle room, made with a cushiony inner layer like memory foam, and locking joints, protecting against dangerous contortions.
I wish i had a physics teacher like you.
GREAT VIDEO ! I always thought about the momentum thing , finally satisfied with your mathematics too.! thanks !!!
My understanding of the momentum issue was that the forces are distributed uniformly through his body by diamagnetic repulsion, similar to the levitating frog demo, but scaled up.
Awsome physics ...but there is no lyks.... can't understand why....but his explanation is very very fantastic
