- What's more classic than seeing a hero swoop in at the last minute to catch a civilian falling through the air? It's an exciting way of showcasing a character's abilities, but is it really as safe as the movies make it out to be? Kyle takes a closer look at the potential consequences of this seemingly helpful service in this week's Because Science.

In words of one thinker of our time:
“Speed has never killed anyone. Suddenly becoming stationary, that's what gets you.”
― Jeremy Clarkson
"It's not the fall that kills you, it's the sudden stop at the end"
I'm not afraid of heights. I'm afraid of ground at high speeds.
this isn't technically true because going from stationary then accelerating at great speed in a short time would have the same effect.
Speed is relative, so... yeah. Of course. It's not the speed that kills you, it's the high acceleration.
@@yourfavoriteskinnynerd1812 well, maybe he can change his phrase to "suddenly changing the module of acceleration is what gets you"
*Loki voice*
“I HAVE BEEN FALLING FOR THIRTY MINUTES!”
@@ticonofruger573 Loki isn't an Asguardian though. He is a Frost Giant...
Probably has similar resistance to injury, but accuracy in the details can be important.
Well, Loki might be falling in a void of space where dr. Strange ported him, so there shouldn't be much acceleration. And yes. He's not human.
@@daltigoth3970 Right
Frost giants seem to have equivalent strength to Asgardians since they have been warring for so long. Otherwise, Odin would have been able to conquer them long ago.
@@daltigoth3970 Loki survived beating from Hulk.
I'll give Shazam a pass since Billy kept skipping school and probably wasn't paying attention in physics class.
What school do you attend that teaches physics to 12 year olds?
@@NinjaBearFilms wasn't he 14?
Anyway, by freshman year I had already learned basic physics (newton's laws, momentum, acceleration, etc) and I wasn't even in advanced classes. Plus we had done the egg drop challenge to come up with a structure to save an egg from a 2 story fall. Go Washington State GO! Lol
Jess_Marie_G I’m not sure, I haven’t actually seen it yet.
@@NinjaBearFilms I can't speak for US schools, but I already had Physics in grade 5 and 6 in Germany. Which is about age 10-12.
@@NinjaBearFilms we did physics on elementary school. Nothing hard but still.
Henry Cavill's Superman does it the "safe way" at least twice. In "Man of Steel", he doesn't just fly beneath Lois' escape pod and stop it; he catches up to it, matches velocity, pulls Lois from it, and slowly lowers her to the ground. In "Batman v Superman", when Lex pushes Lois from the top of the skyscraper, Clark again matches her velocity and then slowly lowers her all the way to the ground. And it's so beautifully shot both times.
Two great super-hero movies!
Ricardo S. Santos idk about that
That's actually most of w..ya know arms and catching, and spidermans stuffs is springing(or usually is or something).
@@ricardos.santos6714 I agree 100%!
Too bad those movies suck.
Super-Hero "Huh... seems I caught another bag of goo; could have sworn it was a person... I don't get it."
If you were actually falling, your hair should have been flowing behind your head rather than hanging below it. The way I see it, there are two possibilities to explain this. Either you weren't really falling, or your hair is made of a super dense material that makes it heavier than the rest of your body, resulting in it being the "leading edge" of your human shaped fuselage. Clearly, the latter is more likely, so I have to ask, Kyle...
What is your hair made of? Is it neutron star material? Is that why it's so shiny and beautiful?
I was going to say the same!
Argon oil?
Gabriel Munoz you goof, everyone knows he uses Thoreal Paris .
Gabriel Munoz This deserves more likes.
Wow, this also has huge implications for heroes like Flash or Quicksilver when they cary citizens to "saftey". The forwards velocity in the citizens would send their mass flying forward when the speedster comes to such an abrupt stop. The speedster would act like a catapult for their helpless victim. They'd have better chances of survival being trapped under rubble or being subject to an explosion.
Love the videos and the crew behind them.
I'm not sure about quicksilver but I think that the flash shares the speed force with whomever he is saving, protecting them from the insane G's in the same way that it protects him. I'm not a comic expert so take what I say with a grain of salt but it would make sense
@@loganricherson That's exactly what happens
The speed force does that. Atleast one comic gave Superman the same thing. Marvel though, just ignores it. Quicksilver can now go mach 5 without Sonic booms too. So something metaphysics screwy is happening beyond simple running really fast.
They'd be dead before that, no difference relativistically between slowing down and speeding up, they can reach insane speeds near instantly, it would be like getting hit by a train!
True just think of Gwen when spiderman "saved her" but then in spidermans web Gwens spine broke
I'm surprised you didn't mention Incredibles. When mr. Incredible got sued for saving people and injuring them
Kaja Sinis I’m also surprised he didn’t mention Quicksilver in Days or Future Past lol
2.5 seconds to fall from a 10 story building.
Light takes 1.3 seconds each way between the Earth and the moon.
So if someone were standing on the moon and watched you fall off the roof of a building that is 10 stories tall and instantaneously accelerated to the speed of light to try to catch you, they wouldn't be able to reach you in time. You'd need at least 12 stories.
You're welcome. I guess.
Man Of Steel coming from the man of steel himself hahaha experience shows
What kind of insane eyesight do you have to have to see someone on Earth falling off a building while you're standing on the moon? The Sauron kind?
@@duffman2625 the content algorithm kind
Let's not forget that the Hero usually hears said person falling before setting eyes on them and sound is significantly slower than light so the time frame would be even longer. Then there is decision and action time etc...
@@foxstarwind99 I have not seen this. Normally what I see is a bad guy puts an innocent civilian or someone the hero knows and loves in danger by falling *right in front of the hero's eyes*, and the hero must make the decision to save said person, giving the bad guy time to get away or complete an evil scheme.

This deserves a footnotes
😂
they don't exist tho
Not in the blatant and overly dramatic sense as shown in comic books and cmb movies, no. But Stan Lee did a whole tv series about superheros in real life. There are some amazingly-gifted people out there who could be fairly classified as superheroic. One guy literally made himself into a cyborg, and is able to go around wirelessly interacting with lights and other electronic gadgets in his home (I don't remember if he could do anything outside the house, though, since it was at a time when mobile devices weren't so prevalent). That proves that for superheroes like DC's Cyborg it's really all about scale (technological availability) and ethics (hacking, end-of-life stuff, body mods, etc). We have supergeniuses, too, so supervillains like Brainiac or the Jessica Jones abuser potentially aren't out of the equation either.
Everything else would probably depend heavily on technology and therefore would have a huge host of issues to be dealt with regarding the fragility of the normal human body (which Kyle and other content creators are busily pointing out). I could see a Batman being possible, for example, but a Captain Marvel or Spiderman would just be ludicrous.
I know this is an "older" video, but it seems a variable has been overlooked which could make faster saves safer - Telekinesis; the ability to move things with your mind. More specifically Contact Telekinesis; using your mind to hold things once you have made physical contact with it. In other words, once you touch the thing you're trying to catch, this power kicks in & essentially provides additional support for the item being lifted/thrown/CAUGHT. If powerful enough, it could potentially work on every piece (every millimeter of metal, every bolt, every passenger, every cell, drop of blood, EVERYTHING) of the item caught to the point of cancelling out some inertia & therefore G-forces. I think it's been used to explain a few times how Superheroes can catch a falling car without it wrapping around them (like Shazam's bus should have), but not often enough however...
Plus most versions of Spiderman's webbing stretches like that of a real spider's web, cancelling out a few Gs there. Would still hurt hitting the windscreen, but he was trying to test chemicals on War Vets...
As a wise middle aged man once said in a British car show: "Speed has never killed anyone, suddenly becoming stationary that's what get you!!

Go from 0 to 10000miles per hour in a second and say that again.
@@MustafaKhan-mj8yv sir that isn't speed, thar is acceleration. Pretty much the same thing as abruptly stopping. Same forces in play. Also we are traveleing 34,000 mph right this moment, and we don't feel a thing.
@@matthewedwards6454 Speed is always relative so one could say that we are moving at 0 mph and another can say 34,000 mph and both would be right
@@maxbuster1508 that was precisely my point. As the op mentioned, speed doesn't kill you, the sudden change does. I was disputing Khan's comment saying that a change in velocity is not speed, for if speed itself was a factor, the earth's rotation alone would kill everyone.

Hey Kyle, I'm seeing lots of comments about the scene from the Incredibles where the man is attempting suicide and Mr. Incredible "saves" him, but after seeing this episode, I rewatched that scene to see if Mr. Incredible would have actually only broken that man's bones, and since I'm "that type", I decided to do the math:
The man (Oliver Sansweet) falls for about 6.5 seconds, reaching terminal velocity (53 m/s).
At the time of the catch, it appears that Mr. Incredible has no meaningful vertical velocity, so I assumed his velocity as 0.
I tried again and again to "time" the impact, but my best guess is 0.1 s and so that gives us an acceleration of Mr. Sansweet vertically of 530 m/s/s or about 54 g's
But that's not all.
Mr. incredible jumps the gap between the buildings (about 14.8 m assuming 2-lane road and lane-wide sidewalks) between the buildings in a little over 1 second, giving him a velocity of, well, 14.8 m/s horizontally.
This means that Mr. Sansweet also was affected by a horizontal acceleration of 148 m/s/s or another 15.1 g's
Using the Pythagorean Theorem, we can conclude that the total acceleration on Mr. Sansweet's body is sqrt(148 m/s/s ^ 2 + 530 m/s/s ^ 2) = 550 m/s/s or 56 g's, effectively killing him then and there. (Also, having the 158 kg Mr. Incredible land on you to aid his rapid deceleration from 14.8 m/s upon landing in the building wouldn't help).
Thank you and have a wonderful day Kyle, wielder of markers and science!
I bet you get *super nerd*😁
@@malachilynch2979 I hope he even sees my comment
"It's not the fall that kills you, it's the sudden stop!"
Jeremy Clarkson had a quote about this exact thing in one of the Top Gear episodes he was in.. he said "Speed has never killed anyone. Suddenly becoming stationary, that's what gets you."
Tony's armor snagging all the people out of the air in Iron Man 3 is a great example of saving people the right way. He fell with them, catching each in turn, and then only pulled up, gradually, when they were close to the water.
I'm interested in whether his technique of making it impossible for everyone in the "monkey chain" to let go (he electrified their arms, so they couldn't open their hands) would work.
Agreed, I was also thinking about this part from IM3.
But then there's a scene where he freefalls and smashes into the ground and nothing happens.
Black Venom he has his armor I’m sure it was durable
@@Geo2wavey The suit may be durable but that has no effect on the deceleration. No suit can prevent a guy surviving a fall from the sky.
What about Tony suddenly pulling a 180 after Loki tossed him out of Stark Tower?
Hey Kyle,
What about redirecting the force into horizontal motion in a curve like divers do?
I was wondering this too. Like in the Matrix when Neo catches Trinity.
@@Doleoh if you mean second movie, then it probably should be more letal, as he not only cancelled all her already gained speed (which was nearly T.V.) but then added another vector of acceleration, which was way above Mach 1 ( judging by the cars, that flyed behind, it was freakin' Mach 100), therefore dismembering her (and probably himself, since he's flying faster than bullet, and he's vulnerable to bullets). Only reason for hero to change falling into gliding is to help poor bastard dodge what's on the ground, or what falls after him. Although IRL, where we don't have flying superheroes (sadly), trading your vertical speed in horizontal might slightly help, if you falling on trees or something, that's scattered horizontally on the ground. Also, before colliding with them, you wanna increase ur body surface as much as possible. True, if it is kind of trees that have branches sticking out perpendicularly, you're likely to be impaled, but if it's kind of a spruce tree (or any other kind of tree that has branches pointing downwards), u might have a chance to survive. Break 1/3 of your bones and have severe inner organs damage, but survive (for at least some time, maybe u give people, that seen u from the ground, time to save you). however, if you falling on the ground, changing direction won't help (unless you're in a wingsuit), there will be around 60 degrees angle between you and a flat concrete. Just in case, i'm not a physicist, neither a pro skydiver, to be 100% sure that everything i said is true, i'm going from my own knowledge (which lacks in both disciplines)
Thats also a good techinque that people that do parkour use. But it has its limits too.
That's the same thing, you decelerate vertically in the end and that's what matters, it's just that in some context this must be achieved through moving horizontally when landing (parkour roll for ex) but you could theorucally decelerate the same amount without the horizontal movement, while be the same result
That’s exactly what I was thinking!!!👍
That scene in "Matrix Reloaded" where Neo comes in supersonic and grabs Trinity before she hits the ground is a great example also. In real life, she would have been instantly killed, like being hit by a Mack truck. Of course, this being the Matrix, and Neo being The One, he probably altered the program where she wouldn't be smashed to pulp by the impact.
Adam J. Harper he said that
@Adam J. Harper At the end of the original film, he explicitly say that ALL laws are arbitrary and can all be manipulated at will. Then, he put down the phone and take flight.
In the programmed reality of the matrix, had Trinity hit the 'ground' she would have died. Not just because the environmental rules of the matrix mirror the real world but in her mind, the shock and trauma of the 'impact' would kill her in the real world. Even though, physically, she never fell at all. But between the Matrix, and her own mind in effect telling her, you cant and wont survive this, she wouldn't. Neo, like everyone is saying, has all the Matrix's god-mode cheats and console commands. So yea, TGM and cushion her fall and subvert all the messy details.
Adam J. Harper: Neo was a script kiddy.
Me: Superheroes saves is dangerous.
My friend: That's BS...
Me: That's Because Science!!
that's one of reasons that the "Supers" were banned in the Incredibles universe. the people that got "saved" got injured. also NO CAPES!
Capes are dangerous, remember what happened to Syndrome? NO CAPES
@@crazylarryjr don't some supers wear capes to help them fly? or is that movie logic?
Jin Tao Yang like the one that dr strange use?
big yes
@@wowbanget3429 like when Supergirl was learning to fly
Actually rewatched that movie the other day, and yeah it started from all the injuries caused by Mr Incredible when saving people, especially the train ones. Something I also noticed however, is that the train things would never happened if it weren't for Syndrome (even though wasn't Syndrome yet)
Glad you mentioned that the first Superman movie got it right.
When my super powers kick in, I'm coming to you for a manual.
Any day now....
It's simple: check the current falling speed (call it v) and height above the ground (h), calculate v^2 / 2h and that's the minimum deceleration you have to apply to touch the ground by the time you stop.
Higher deceleration is OK as long as it's something a body can cope with. However, you'll stop above the ground so you won't be ready to offload the person you rescued until you reach the ground.
Lower deceleration, on the other hand, means that you and the victim will hit the ground, albeit at reduced speed.
I already have a super power. I can become invisible when nobody is looking at me.
@@goktimusprime I can turn invisible in pitch black. Unfortunately, when I'm invisible, I can't see.

“ please stop catching us like you catch a bullet “ I’m dead
"That conductor is conduc-dead..." 🤣 I was conduc-dead after he said it
At least in Hancock, this concept of "superheroes save people incorrectly" is explored. That train derails causing untold damage, death, and destruction.
They actually do cover this in the first Incredibles movie and comic book Spiderman with Gwen Stacy. The catch in the Incredibles leaves an attempted suicide person in several casts and Gwen Stacy's neck snaps due to the Gs and acceleration still happening on the rest of her body.
I love the show and your commander style... keep it up... Kyle.
i think the incredibles one has fake casts, to win more money with the law suit

Hey Kyle! Just a quick question or correction, but wouldn’t the bus still crumble as Shazam catches it?
Yeah, it should have just impaled itself on him.
Everyone remembered Mr. Incredible before watching this video?
I think you broke something..... EVERYTHING!!!
Yes, but he wasn't stopping the vertical fall distance; just merely re-directing it into a horizontal force. The point at which the force direction changed would still hurt(the guy is shown in a sling and neck collar) but would ultimately save their life.
@@MrCreamster20 actually, thats not exactly how that works, because if you look at the clip, Mr incredible actually decelerates the man vertically and adds horizontal acceleration to the mix in about a tenth of a second, which actually increases the g's pulled by the man
The point that The Incredibles makes is that simply catching people or stopping trains is likely to cause injuries to the people that you're trying to save. And yeah, people will take legal action to cover things like medical expenses, loss of income due to being unable to work and other forms of compensation.
Supers were literally becoming too much of a financial burden/liability for the government which is why they were shut down. The Incredibles is one of the more grounded-in-reality superhero movies out there.
Same!
Your hair didn't obey phisics when you where falling
Wonder if this comment makes it to supernerd lol
He was in the void y’all, physics works differently
That's his superpower
Physics doesn't apply in the Void. He already said, in the videos, he is not standing on anything but rather, floating. If gravity doesn't exactly keep making sense, why would it when he falls. (We all know what has been edited out)
Argan oil does magical things to your hair... ;)
me when i hear about instantly stopping:
G's, here we go again
peter Parker learned that lesson the hard way
RIP Gwen Stacy, if peter payed attention in math class you would have lived
That's one of my favorite superhero scenes, because it shows that things aren't as "simple" as we the audience would like to believe. Also, the pure emotion of the scene.
It wasn't really Spidey's fault. If he didn't try to catch her she would have died on impact with the ground.
Didn't she die because she smashed her head on the ground, because Spiderman was a bit late to catch her? Or am I thinking of the wrong scene? Because I remember her head bending a little bit upwards after hitting the ground, what would be deadly. If you think about it, spiderman could be one of the superheroes to save you safely if he just applies an amount of flex in his strings of Web like the ropes climbers use, that stretch when you fall, so they still slow down your fall, but not instantaneously like Kyle asks for.
Have a nice Weekend and never stop instantaneously
In the comic the sudden stop snapped her neck.
Yes, because in a split second moment to save someone's life you're going to stop and do the maths.
Oh god thank you for not talking like that in the entire video.
That's something I liked in Iron Man 2, when he flys in to save someone from a drone-bot, rather than just flying by & grabbing them, he comes to a complete stop for just a moment before picking them up & flying off. Same concept
Episode idea: Is Superman's power really control over Inertia? Would explain most of his powers such as flight, speed invulnerability, etc.
Superman being a kinetiscist is a fairly old idea. It's about the only way anything he does could make any sense unless you live in a universe without newtons laws.
(me, having not normal amounts of knowledge on superhero powers)- ya know.. Superman has a sort of force field all the way around his body (and can extend it to other things/people, but it's all subconsciously), but it factors into why he is bullet proof, can't get dirty, ect. (Fact fiend made a video about it a few days ago)
Maybe that's how Superman can do it, but other heroes are.. not suited to it. (Rip Gwen Stacy)
I think DC described him as having the capability of distributing his strength through the entirety of objects, Shazam as well. Their strength is more about will than muscle... Thats how Billy could cath the bus by the windshield.
I was rock climbing and fell using a climbing rope..
I was in a short free fall (very short lol..)
There is a built in stretch in the rope... when it caught me I was still “falling” and then I hit the end of the stretch ..
It still was a hell of a jerk..
But I really appreciated the elasticity...
The difference between a static and dynamic rope.
Hi Kyle ! Thank you for bringing this issue. This probably means that the Sokovia Accord should include a clause concerning a super hero saving a falling human. In order for the law to have an effective number, it should probably include the human terminal velocity (55m/s) and an overall "safe" deceleration (for the sake of the argument, let's go with 10G). Based on your math, this gives us approximately 0.56s to safely decelerate a human body from its terminal velocity. With adding a safety value in place, the law could say something like: "In the case of an enhanced individual saving a falling innocent, said individual should prepare for a 1s deceleration after catching the innocent. If this deceleration was possible but not accomplished, any resulting injury should be the enhanced individual responsibility." It may also add that any cellphone could be used as evidence since it seems like in every movie, everybody is faster to pull out a cellphone to film a fall than superman to catch the falling person... We draw faster than lightning ! :-D
Hey fellow SuperNerds out there. Two time SuperNerd here (Kyle credits me with a third but he actually gave that to my son, something he is very proud of and I won’t take from him!) and I know this is not related to today’s video.
So I do not expect this to get into footnotes.
But there is another UA-camr that has made a working Infinity Gauntlet out of Brass and says that he will give it to our favorite Science Boi stuck in the void to play with and make a follow up video to his previous video about the Thanos Snap.
ua-cam.com/video/jnFA7rODuAQ/v-deo.html
Yes, it really does snap contrary to Kyle’s initial conclusions. But, I’m 100% confident that he can explain why this gauntlet works when his test gauntlets did not.
So please, like and comment on this post to make sure that Kyle Hill sees this as he collects all of your nerdy comments and corrections for this week’s video about how super heroes should be saving us all from being thrown from tall buildings by the villain of the week.
And hopefully we will see a collaboration of my favorite channel on a follow up with a “working” infinity gauntlet.
This is too much power for mortal men! WHAT HAS HE DONE?!
The idea of a snapping gauntlet depends on how well it fits, as well as how malleable the metal is under force. EG you can snap your fingers while wearing a rubber glove. If it analogs to a similar effect in Thanos's hand, no issue. And with the reality stone, it easily could.
Congratulations!
Nasturtium I made a cosplay infinity gauntlet that snaps, but mine is made from a gold fabric which is what I suspect is the difference in play here.
I can explain it, although not quite as good as Kyle would. The MCU Gauntlet, along with the ones that Kyle tried, were all metal on metal, which doesn't have as much friction making the force of your finger when hitting your palm not that much to push the air out of the way causing the sound. Also the metal wasn't able to mold as easily to form the air pocket which contributes to the sound of the snap. The gauntlet made in the video has a leather glove used for the palm side of the hands and the design was just on the backside of the hand. I use to wear leather gloves, and I know it is possible to snap using them, just harder. The leather does have enough friction to give your fingers enough force to hit your palm to cause the noise and also is able to flex enough to form the air pocket in your palm to give you the snap. What he did was just have that glove and put accessories on the backside of it to make it look like an infinity gauntlet. I am in no way shaming the creator for the content, because it is a good looking build, however he did call Kyle out on it and is treating like a "I proved him wrong", when he didn't even make both sides of the gauntlet.

Superman at least in the comics says he has to calculate all kinds of physics instantaneously before moving.
I saw Jimmy hit his signal watch just before the Gunshot and i could see Clark's reaction.
As soon as he heard the subsonic squeal, he would focus, instantly calculating things like longitude, lattitude, range....than he would fly he once told me it took him years to acclimate this kind of speed.
In space it's all fun and games but on Earth he has to calculate subtle pressure dynamics, airflow, inertia and so on, he almost always slows down over populated areas in order to eliminate the Sonic Boom.
As for the aforementioned Space he showed it on another occasion as well
He quickly leaves behind his usual earthly perceptions, he won't need them now some concepts must be allowed to live in the mind unencumbered by traces of Human skepticism.
Space bends around him at this speed and time slows down there is no room for judgement only action, this is Super Speed.
Hey Kyle what do you think about the scene in Iron Man 3 when Iron man has to save about 10 or so people falling out of a plane?
Would having them link together as they fall, combined with dropping them off in the ocean and a slight upward acceleration from Iron Man pulling them really be enough to save them?
@Another Faceless Name he used electricity to close their hands so they wouldnt accidentally drop each other so it wasnt up to them to drop someone else
Wait it wouldn’t matter about electrically locking there hands it would still come down to how strong there hand muscles are. If they are not strong enough to maintain the load the grip breaks just like to heavy a load breaks a metal chain
People! Please like this comment so that Kyle answer it in the footnotes! Oh no that's on Twitter right? Put this question there! I wanna know!
A humans muscles are actually stronger than they are allowed to be. Even the weakest (normal healthiness) person has enough potential muscle strength to break their own bones. This can can be seen in people who are effected nerve agents in chemical warfare where they break their own bone from every muscle fiber contracting at one time. Hypothetically if an electrical pulse was to activate ever muscle in their hands all in line they wouldn't possibly be able to hold on but doubly so would be at risk of crushing each persons hand into pulp. We have a built in regulator that prevents us from over using our muscles so we don't damage ourselves. This also happens in the situations where you hear about mothers flipping cars to save a child. The panic turns off this regulation.
IIRC, that scene was mostly done practically, with skydivers, just editing out any footage of parachutes. So if IM was able to slow them to parachute speeds, then they should be fine.
Shows scene that people use to debunk heroes catching.
Most scientifically acurrate scene for heroes catching.
I live how you take all this time to breakdown these issues in these movies and explain the real physics behind it, but the fact the guy is flying doesn't get a second glance
Wouldn't the material at the front of the bus have failed and basically fallen THROUGH Shazam! and still crumpled into the ground?
Love the show Kyle. If ever you're able to squeeze in a "HEY LIV AND RILEY!!!", my whole family would poop our pants :)
That's exactly what me and my brother instantly thought when we saw the movie
yes, and that's why superman can't save airplanes.
Pretty soon your claim that Superman can't lift a building by picking up on its edge!
Less through and more around, but yeah. Unless Shazam! is able to spread out his strength like a field to increase the surface area of contact with the bus, the bus would just crash down around him, and he'd be covered in engine and passenger.
like a nail to a soda can
Next time you do the "falling" stint, film it upsidedown and on your back. Fan from above.
There's one thing that wasn't considered in the math. If the superhero used SPACE (distance) to save someone from a fall, it would increases the deceleration time substantially.
If instead of moving vertically they moved diagonally they could change the direction of the force in small angles increasing the distance and therefore time. I just can't do the math to find what angle would be safe to redirect a person without putting them under to many Gs when doing so.

Spiderman's webline's elasticity does help with slowing down before stopping.
Tell that to Gwen.
@@samuelfrye7629 Gwen smashed her head on the ground, if he'd caught her sooner she would've been fine.
@@aliciacordero7436 No, it was (as initially thought) the sudden stopping due to the webline that made her neck snap (it was revealed later that she was already dead when Spidey caught her). But she never hit the floor.
Spiderman is a scientist and his powers actually give him super thinking ability for certain Spider related stuff. He knows and actively adjusts how he saves or catches people because of it. Even in the comics.
Two comments:
Firstly, you would also want to catch the falling person using the greatest surface area possible to prevent them receiving targeted pressures.
Secondly what about transferring energy in other ways, for instance parkour techniques cause forces to be divided to multiple points over a a longer period of time.
Cue Spiderman schooling other superheros on the physics of deceleration.
its funny how the bus would crumble if it hit the concrete, but when shazam catches it, focusing the point of impact to the size of 2 hands, the bus stays whold and doesn't even bulk in around his hand..
that said, this episode reminds me alot about game theory and the recent spiderman game.. how spiderman is killing everyone :D

to be fair flash would be in the same pit, but then again quicksilver's speed could be working like the speedforce, and some sources when flash saves people the speedforce is extending to what ever he is holding/saving, thats why his pants stay on instead of flying off, might be some personal gravity field or something.

I saw a comment about Loki falling for “30 minutes” and wanted to respond.
I think there are two reasons Loki or is fleshy humans might survive such a fall. 1) when we see Loki disappear thanks to Dr. Strange we don’t know where he goes. If he went to somewhere where there are no forces to act on him then he would continue to move at the speed the enters the portal without accelerating until he exits. This could total maybe 2 seconds of fall time. 2) He may have been falling under lesser gravity or thicker air. Under this condition Loki would reach terminal velocity much faster and (assuming gravity weak enough or air thick enough) would me moving far slower then if he had spent that time falling through the regular atmosphere.

Great work Kyle! And using the superman movie clip [known to discredit hero rescue] as the BEST way to save lives is fantastic! Many people wont be using that reff anymore. Love to see more stuff like this with effective ways for superheroes to save lives and make the world a better place to live.
Hey Kyle
Great episode :)
I know most super heroes are saving us wrong. However, does that mean Tony Stark in Ironman 3 saved the flight crew the correct way, or at least, a more realistic way. Would that many people falling, all holding hands, in positions that that create the most wind resistance, and being guided to the water work at all? Or would the impact with the water put everyone in the hospital rather than having them wave goodbye to Ironman?
Take Care and Be Well
I'm more concerned with their arms getting ripped out. if you've heard of a wingsuit, there are people who can land those without a parachute, so the concept is more than possible, it's been done. But with most of the lift provided by the mark 42, and the increased horizontal speed needed to compensate for the lack of wing suit, I'm not sure the ligaments will be able to hold. maybe with four people, but probably not the group of several that he had.
@@manamongmen3381 with the lack of wingsuit being key, so slowing down would be difficult, say the "static charge" used strengthened their limbs to accommodated the strain, what speed would they hit the water? Only human surface area to slow them down, would the water landing be survivable?
Landing in the water would be survivable, as they would be going faster horizontally than vertically, thus skimming it until they slow down enough to sink, though it would likely still be dangerous. I don't have the patience to do the math right now though. There is definitely a chance it's lethal.

Spider-Man would easily be the most ''safe'' superhero. He could make a web net connecting to another building, decreasing the velocity per time, or, just like in Spider-Man 3, he could reach to that person falling, catch them(yes, he can, even if the time is slow.) and then shoot a web at the building, decreasing the velocity.
Does this remind anyone else of that episode of the big bang theory where Sheldon says that by catching Lois Lane, Super is slicing her into 3 equal parts?
It's exactly what I'm referring to. He's wrong. -- kH

And he'd still have expected gratitude.
"Ha, I saved yo- WHAT THE F ROXANNE!? YOU AREN'T SUPPOSED TO DIE WHEN I SAVE YOU. You could've just said, I don't know, thanks before you bite the dust."
I'd like to point out that Spider-Man (ever since a certain incident with Miss Stacy) has canonically always applied his webs in such a way to have give and act as impromptu nets or bungee cords.
Also, you know you showed Gwen Stacy at least twice in today's episode, right?

Obviously, Spiderman killed Gwen in the original comic because he couldn't reach her in time.
In the ultimate universe (I don't remember the number of the issue) to save a child falling from a building he embrace him and slows down the fall because otherwise he would have killed him.
Also, that's how the flash catches bullet in midair, by slowing them down with is hand
Henry Cavill supes save Louis the right way in batman v superman
An object which is falling through the atmosphere is subjected to two external forces. One force is the gravitational force, expressed as the weight of the object. The other force is the air resistance or drag of the object. If the mass of an object remains constant, the motion of the object can be described by Newton's second law of motion, force F equals mass m times acceleration a:
F = m * a
which can be solved for the acceleration of the object in terms of the net external force and the mass of the object:
a = F / m
Weight and drag are forces which are vector quantities. The net external force F is then equal to the difference of the weight W and the drag D
F = W - D
The acceleration of a falling object then becomes:
a = (WD) / m
The magnitude of the drag is given by the drag equation. Drag D depends on a drag coefficient Cd, the atmospheric density r, the square of the air velocity V, and some reference area A of the object.
D = Cd * r * V ^2 * A / 2
Before watching: It is not fall that kills, but sudden stop.
Edit
After watching: Just like why you do not do superhero landing.
Instantaneously stopping something dead on it's track right before it hits the ground is basically the same as letting it hit floor, it's so dumb but it gets right over our heads while watching movies
So in The Incredibles, when Mr. Incredible saves that one guy he likely would have just died immediately anyways. Or would the change in trajectory count as deceleration? He is falling down only to suddenly start going sideways through the building after he gets tackled in midair. I’m curious what Kyle has to say about this.
Well he fell like 5 floors that can be survivable I guess. If Mr Incredible didn't do stopped him he would have fall like 10 or 15 floors and way beyond the point of no surviving.
A B.S. P.S.A. huh? Lol Hope no one else read that the wrong way.
How can you not trust a BS PSA, right?
Oh, I fully believe the pun was intended.
I hope EVERYONE read that the "wrong way" because I'm pretty sure it was intentional. Tis not Kyle's first reference to BSing.
For everyone asking if catching the victim at an angle or on a curve would give you more time to save someone: momentum and velocity are directional. That means that no matter how much horizontal force you apply, it does not change the amount of force required to counteract the vertical mometum. Assuming relatively flat ground (i.e. you're not immediately next to a large cliff), adding horizontal momentum does not change the amount of time you have until you hit the ground.
So, Kyle (or is that Ky-El?), while I'm sitting here, leg up after I did my knee in falling off a bouldering wall just 2-3 metres (when a metre makes a difference, do you measure from centre of mass to ground, or feet to ground?)...
In that Shazam! bus catch, as I was watching it, and the bus passengers were falling through the bus towards its windshield, I really thought they might have a darker moment, and they might just fall right through the windshield, adding all the broken glass cuts to the sudden stop at the end outside the windshield (maybe not such a thing with modern vehicle glass; we're not talking plate glass windows here). But no, they chickened out, and had them land 'safely' on the glass, although I think it started cracking just enough for drama. I'd also note that, if you're looking to give them an out if the bus had hit the ground with the body crush distance (BUS body, not passenger body!), you might take into account that it should have crushed as much and more from Captain Marv- I mean, Shazam's catching it, with the force distributed over a much smaller area, basically cutting through the bus while slowing it down, until it hits the ground anyway and Capta- Shazam finds himself standing in the bus, its shattered windshield (whether or not from falling passengers) around him.
Final note, way back in my nerdy days (who am I kidding?), playing superhero role-playing games, I had a hero character with gravity-based superpowers named Terminal Velocity. OK, maybe more of an anti-hero, in today's parlance. Emphasis on the 'terminal' part.
Love the show; I guess you could say I've really fallen for it! Augh, my knee!
The everyday use of the term "free fall" is not the same as the scientific definition. In common usage, a skydiver is considered to be in free fall upon achieving terminal velocity without a parachute. In actuality, the weight of the skydiver is supported by a cushion of air.
Freefall is defined either according to Newtonian (classical) physics or in terms of general relativity. In classical mechanics, free fall describes the motion of a body when the only force acting upon it is gravity. The direction of the movement (up, down, etc.) is unimportant. If the gravitational field is uniform, it acts equally on all parts of the body, making it "weightless" or experiencing "0 g". Although it might seem strange, an object can be in free fall even when moving upward or at the top of its motion. A skydiver jumping from outside the atmosphere (like a HALO jump) very nearly achieves true terminal velocity and free fall.
In general, as long as air resistance is negligible with respect to an object's weight, it can achieve free fall.
If i remember correctly, in BvS, when Superman saves Lois Lane after Lex pushes her, he does fall with her and slowly stops before puting her in the ground.
But I might be wrong.
Oh! And what about when the Hulk catched (crashed) Iron Man in the first Avengers movie? They kinda slowed down before hitting the ground.
first, sorry for my bad english in case i make a mistake
But, how about graving the falling person by the leg, and make a circular movement, so transforming the linear down velocity into angular velocity, and throwing the person up, somewhat making a U shaped move, then the hero would have the time to eventually slow the falling person into a more controlled non fatal velocity... would that work?
If it didn't rip the leg off
If they swing a person out of vertical drop into a parabola/U-shape, then the superhero is just adding more unnecessary velocity into the system. Imagine the scenario you just described, but your "U-shaped" swing doesn't have any horizontal velocity at all: the person just decelerates straight to the ground, reaches zero, then accelerates back up. That, my friend, is just bungee jumping :) The *minimum* force a person can experience is a constant, linear deceleration which reaches zero exactly the moment they contact the ground.
Couldn't you just redirect their momentum in a more gradual way? Such as the arc f(x) =e^x makes. There would still be a high amount of G's pulled but, It should be substantially less than what it takes to kill someone. Right? 🤔🤔🤔
Doesn´t the redirection process have the same problem? You would pull to much g when it happens instantly so its a question of how fast you would redirect and how strong. So you would have to do it as slow and flat as possible and as fast as necessary. But you would still have to catch the person. But it could give you a little bit more millisec and that could be relevant.
Yes, that would work. Less G for a longer time is the exact same solution.
Actually you can see on you tube babies and children being caught as they are dropped from buildings that are on fire and such. The catchers always try to reduce the impact with an arc.
It would be worse than straight line deceleration because you've increased the applied force by adding force in another dimension.
I should read comments before I post. I said the same thing without the math.
you don't need to add force to go sideways you can convert their built-up potential
you also don't always have straight line capability only ever going straight would be substantially worse for your body
its more important to give your body more time to stop even if you go sideways or hyperbolic back up
the force on your body to produce a side ways movement over time is much less than stopping over the same distance
its why just doing a roll produces less instant force on the body

why you could survive freefall if you had a slide though your going to have to find a way to slow down once your going horizontal

Thank you for this. I've considered this for my own fictional writings and I'm happy to see more people discussing this.
So heroes need to slowly decelerate people and not be a jerk.
HA
....
You know, like the jerk function?
....
I'll just....leave now.
I once searched the names for things similar to jerk, acceleration, and velocity, and it's just too weird it's gross xD
Because science: “This is a B.S PSA”
Peter griffin: That means two things!
I don’t get it?
I knew this as a kid.
The impact of Shazam catching that bus is pretty much same as it hitting the floor. I can't believe the writers didn't spot that obvious flaw.
What if the hero swooped down in an arc, gradually changing the falling person's downward momentum into a slower sideways momentum?
The ol' swoop and scoop
That would probably only be beneficial if you got the person running or rolling somehow so they convert some of the vertical momentum into horizontal momentum when they reach the ground. The amount of time available to decelerate wouldn't really change regardless of the path you took because the vertical distance available remains the same.
This is exactly why rolling when you hit the ground can let you jump from higher distances. It works because some of that velocity is bled across the time you skid horizontally on the ground, and that precious fractions of a second lowers the forces you endure.
That's not how momentum works. Your x and y momentum are independent.
@@stevenpurtee5062 what did you just take highschool physics?
Arcing it would cause acceleration perpendicular to the arc's tangent, reducing the y momentum, you should have learned that anyways.
@@Artameful , I am a college Physics and Mathematics professor. I know what I'm talking about. You can't decrease momentum in the y-direction by adding a force in the x-direction. That would only result in MORE total momentum. This is basic conservation of linear momentum.
have you thought about the superhero potentially swooping in, and grabbing the fall victim in an arc?
That should essentially make it so there is enough space to safely decelerate.
Next time i fall from a tall building and a super hero tries to save me, i will say no thank you.
Superman=Gravity Control, Captain Marvel=Magic, Spider-Man=Elastic Webbing?
"Hi, I'm the Internet's Kyle Hill."
Me: *LIKE*
My Physics teacher constantly told us there is no such thing as "deceleration"; it is instead "negative acceleration".
Couldnt another way to save people be to change the direction without losing velocity? Like if superman turned a regular verticle drop into a more fish hook style catch so that the person saved would be able to have more time in the air without going splat.
This is more for those situations where there isnt enough verticle space for superman to decelerate safely in just the verticle direction
Changing direction can be visualized as the sum of multiple forces that align on the X, Y, and Z axes. For the sake of deceleration in the Y axis you still need to decelerate on the Y axis gracefully.
Yes, and you can see this in all forms of sports and play. BMX riders, snowboarders and skaters in half pipes, skiers coming down off a jump or using a slide at a water park. All of them land on a ramp to changer the vertical velocity into horizontal velocity.
@@TheDavemarz ppl that practice parkour do it all the time when landing, usually rolling
@@cerdi_99 Exactly. Think about what they do. they land on their feet immediately start to break down to a roll. They are increasing the amount of time to absorb the energy. First absorbing some of it vertically, the time between when their feet hit the ground and when their shoulders touch the ground. At this point they roll forward taking the vertical energy and converting it into horizontal energy which they burn up rolling forward.
@@TheDavemarz I know, I just pointed it out as an example

I was thinking about the elasticity of his spider web. Surely that could help. It's not an I - beam, after all.
MatPat made a video about this.
Is that how parachute works?
Also what about falling down but rather than slowly slowing down while moving into the ground, the person slowed down into the ground by moving downward and also sideways like a slide, for example athletes that do extreme sport like snowboarding and skiing, they do sometimes jump from a ledge before landing on a slide safely
5:28 "that person might pull around 200 g (grams)" ... Doesn't seem to be too bad.
Seriously though, that G has to be a capital one, doesn't it? :D

No, the Earth's gravity is defined as the lower - case "g." Where G comes in is the Universal Law of Gravitation where G1 is the gravitational pull of one object (most often a celestial body) and G2 is the gravitational pull of another object. (also usually a celestial body.)
