- Hey everyone back with Trailmakers! Today we are back in sandbox trying out a supersonic experiment, that is to see if we can break the sound barrier just by falling! I've seen a lot of sonic boom experiments before but I don't recall seeing anyone test how fast we can just fall towards the ground...

I love how scrapman does it accidentally when trying to do it with party balloons 😂
That was with a aero-glitch tho. All the things that was in fron og his cockpit had hitboxes that negated the aero, thus rendering the cockpit aero-less when detatched.
@@megatryn didn't realize that, nice catch!
Ikr 🤣🤣🤣
@@megatryn he still did break it with out trying to so that means he did it in a fair way
@@Jump_Today Rightly so, I was just explaining the reason why he managed to and the glitch.
man, The top doesn't kill you, you'll just hit it like a wall border
Touching it wasn't worth the risk of waiting 5 more minutes, he would have gained maybe 30 km/h.
Adding weight ABSOLUTELY increases terminal velocity, if you keep the drag the same.
Mass does help fight air drag and thus does mean faster falling when drag is significant, which it is when you are going all the way to terminal velocity.
adding more weight in real life won't make it fall faster (given same drag coefficient), however, it will increase terminal velocity. I didn't matter much in your case since the terminal velocity was already above the speed of sound, but if it hadn't been above the speed of sound, then it would have allowed it to be.
The weight simply won’t matter whatsoever as long as the drag is same. In vacuum no matter the shape everything falls the same speed.
@@alkestos except it does matter in this case. Gravity accelerates all things at the same rate, that is true. And aerodynamic drag force vs speed is essentially the same in the 2 weighted builds Kan tried.
However Acceleration = Force/mass (f=ma rearranged) so the force of drag has a lesser acceleration (decelleration) affect in the heavier vehicle for the same given velocity.
Terminal velocity is reached when the drag decelleration = gravity = 9.81m/s2 (on earth), which for a heavier object requires a larger aerodynamic force which the vehicle must be travelling faster to occur.
You can see what @@Dakakeisalie's talking about in the video as Kan's accelerating noticably faster on attempt 3 at 1300kph than attempt 2 at 1100kph.
@@alkestos yes, if drag is 0 aka vacuum, it does not matter and there is no terminal velocity in a vacuum either, but A=(W-D)/m, W=g*m, so you can rewrite it as a=g-D/m. As you increase mass, you'll increase the acceleration as long as you don't also increase drag.
If the terminal velocity is higher then it by definition falls faster
You should do an eggdrop style competition, where the winner is the first person to the ground from the ceiling without breaking any blocks, and no power cores.
I got a scam reply on this from a fake account called @fficial_KanGaming so thanks for removing it
yesss my boi hoppin on the supersonic train NYYEOOOOOOOOO BOOOOSH
Choo choo.
7:41 the only way to make it more aerodynamic is to add more 4x1's to the back like a mirrored tip. it'll let the air flow smoother and thus help you speed up faster.
The 3rd craft with the horizontal balloons was rising at 120kmph at first. That's like freeway speeds. I'm guessing that's a pretty scary experience in real life to be going up at 65-70 mph. Imagine the windspeed of sticking your head out a car window on the freeway
Love the content kan, Can't wait for you to do a up to date air battle
This reminds me to one "best builds" video of scrapman where he showed a creation that broke the sound barrier just with gravity
Felix Baumgartner was the first person to break sound barrier in free fall.
True. Can't believe it's been 11 years, since he jumped from space down to earth.
Crazy guy. 😆
@@error404fnf As a fellow countryman of Felix, I'm glad, someone mentioned is name, and I'm kinda bummed, that kAN didn't know.
Yeah, has been a while, hasn't it?
And what an event that was!
Felt like the moon landing! xD
It was amazing! :)
And I'm still super proud lol
@@loerichson But to be fair, it's kinda hard to follow all the craziness going on, on earth.
For example: If a coworker of mine didn't mention the SpaceX program, I would have totally missed the lauch of the first roket. And boy, what a show this was.
@@error404fnf sure, absolutely, especially these days, eh? ^^
Oh, yeah, didn't know about it either until after the fact. It's funny though, how on the one hand they said it was a 'failure' because it blew up, and then on the other side they said, it was a 'success' because it managed to take off.
And You as a pleb sit in the middle and think, 'So what is it now? Yay, fireworks!' lol
Felix Baumgartner did actually break the speed of sound in his fall, just in thinner air.
It's raining giant burning brussels sprouts!
an objects fall rate in a vacuum is its ideal rate of fall and its air resistance to weight is zero. air resistance reduces its rate of fall relative to the surface area. as an object gets heavier without changing air resistance, the ratio of air resistance to weight will get smaller approaching but never reaching zero allowing the object to accelerate closer to how it would in a vacuum. so in an atmosphere a lead feather will fall much faster than a real feather and its fall will be more similar to its fall in a vacuum. adding weight helps your fall vehicle fall faster.
terminal velocity just left entirely the instant aerodynamics were added, huh
Great video kAN!👍
It is very rare to see kan using wedges
Scrapman did this accidentally on his last video with the small ballons
4:41 RCE Approved
4:42 this is the point my parents would walk into my room
nice job :)
scrapman did this accidentally in his balloon video
Amusing thing just add the most aerodynamic pieces on top and it registers it as aerodynamic even if it doesn't look like it
Density also affects falling speed in a fluid as objects with less density fall slower until they are less dense than the fluid and then they float.
Can you make a glider that can break the speed of sound then pull up and land safely?
Adding more mass does not make an object accelerate faster (assuming identical coefficient of drag). but adding more mass will increase the force air resistance needs to exert in order to match the gravitational force. Therefore the craft will eventually reach a higher top speed even though it accelerates at the same rate.
Assuming the same coefficient of drag and area, more mass does make an object accelerate faster. If it didn't, they would have the same terminal velocity.
If the object is moving in air, and the force from drag is identical, but the force due to gravity is larger for one, that means the net force is larger for it so it will accelerate faster.
The easiest way to consider it is by considering the 2 options are the terminal velocity of the lighter craft.
The lighter craft has the forces balanced so it is at terminal velocity, i.e. its acceleration is 0. The heavier object has a greater force due to gravity so it is accelerating at a different rate.
1:07 Hehe he made the funny shape
adding weight may not make something fall faster
but increasing density, which the weights DO accomplish in this case, will increase the terminal velocity in atmosphere
"Something. Something. Something. Science."
KAN USED WEDGES! WEDGE GANG LIVES!
Should have added more weights to see if you could get going faster with how easy this ended up being.
Increasing the weight, and thusly terminal velocity, would cause the loss of acceleration from approaching terminal velocity to happen later, allowing more speed to accumulate before hitting the ground.
Heavier objects are less effected by resistance. So if there is any resistance in the air it should have more speed - if there is zero resistance in the air it would fall at the same rate
Think acrapman did this already,but good video lol
Adding weight does make things fall faster because mass attracts mass and if something is heavier gravity will have more of an effect on the object.
Gimbals are faster than balloons
More weight is more gpe (gravitational potential energy) and the more gpe there is the more can be transfered to kenetic ennergy
Is a supersonic freefalling terminal velocity possible in real life?
kan do you intend to return the game Plasma ? - I enjoyed the Demo, Id love to see more of the Early access now its out.
Just a question/suggestion....
Would adding fins at a angle at the tail in that caused it to spin (rifling) help???
Just a question
It would stabilise it but the added air resistance would make it a lot harder to reach the speed of sound.
Rifling on rounds adds to the aerodynamic stability, making it fly straighter. This would not help to fall quicker and would actually be a hinderance.
(No idea if this is how it would work in Trailmakers, but this is how it would work in real life)
I think I understand what you were trying to think but the spin stabilisation would also cause slightly more drag due to an increased air velocity over the surface of the vehicle as the air would be traveling root( fall speed^2 + surface rotational velocity^2 ) and the surface drag would be greater than the drag going ‘straight’. It wouldn’t be a lot as the spin would have to be very fast to severely impact it, but it would have some adverse effects.
In the real world, the effects of the increase in surface drag would mainly come from the heating of the outside of the vehicle, with the transfer of heat energy into the vehicle being energy that is not kinetic energy.
Bullets do not suffer greatly from this as they are traveling very fast with very little surface rotational velocity as that is proportional to the radius (which is quite small compared to a vehicle)
@@communistpingu5255 thank you just an idea
i'm impressed
I wonder, if you put your nose-wedges in 90 degree rotations instead of 180 degrees, kinda like a swastika if you looked at it head on(just make sure you use the correct direction), if your block starts spinning around its axis.
I believe scrapman has that happen when he tried to break sound barrier with ballons
It does and it MASSIVELY reduces your max speed
Hi
Your videos are sick. I love them.
Me
Actually adding weight will make it fall faster (IRL). Because you are distributing more weight across the same aerodynamic "surface area", it will resist the drag more, thus fall faster. Of course this has diminishing returns because the ratio of force to drag trends to infinity (AKA the behavior of zero drag) Newton become fig
TLDR; The difference between a falling piece of paper and a falling scrunched up piece of paper. Try it at home if you doubt me.
Man, I made that harder than necessary...
More mass would accelerate slightly faster, since the force of gravity scales with mass, while the force of drag has no relation to mass. At first, the difference would be negligible, but at the higher speeds, it's much more pronounced.
There are people saying the only thing it affects is terminal velocity, but I think it also should impact acceleration too.
can we stop the war
how does F = g???????????????????????????????? How???????
It doesn't affect acceleration. A hammer and a feather dropped in a vacuum would hit the ground at the same time.
Force of gravity does not scale with mass. However, air resistance works against momentum, which means mass affects acceleration due to gravity in an atmosphere.
@@floppaquest4916 it does in an atmosphere. Air resistance works against momentum.
It would, just based off of force balancing. Wouldn't affect initial (and also maximum) acceleration as that's limited by gravity and additional forces.
@@covenantslayergaming6362 Would at v=0, you mean. Ag will always = 9.8m/s^2 (within the parameters of our experiment), and drag will be based on velocity of object, coefficient of drag, and drag cross-section. However, the drag force's ability to work against the mass of the object being pulled by gravity will apply a different amount of Newtons (and thus reverse acceleration) with different masses. But yes- maximum acceleration is indeed dictated by gravity, and flow velocity. At v=0, A = G.
Haven't seen any mathematical explanations, but yes adding extra mass does help.
In classical physics, a force is defined as F = ma where 'a' is acceleration and 'm' is mass. Gravity causes a constant acceleration of 'g' (9.81 m/s^2) for every object regardless of mass. The acceleration will be the same, but the force (F = mg) will be greater. Unlike the force of gravity, air resistance only depends on surface area and velocity, not on mass. Therefore the equillibrium between the forces (your terminal velocity) will be at a greater velocity with greater mass, as the force of gravity will be stronger, but the force of air resistance does not change.
Conclusion: Adding more mass does not increase acceleration, but it does increase your terminal velocity which in this case allows you to hit the speed of sound.
It also increases acceleration, in a manner of speaking. Decreases it slower would be more accurate, since obviously maximum acceleration of the object is at v=0.
It's also correct that Fd will be dependent on velocity, and not mass, however, the action of Fd against an object is directly proportional to its mass.
This is incorrect.
Since you want the math approach, there are multiple forces to consider.
First we have the force due to gravity, as F=g*m.
Then we have the force due to air resistance, which we can simplify down assuming the objects are identical in size and shape. Depending on how simple you want to go, you can have F=c*rho*A*v^2/2, or F=k*v^2.
These are in different directions, so we have the net force as:
F=g*m-k*v^2.
And we know that F=m*a, so:
F=g*m-k*v^2=m*a
a=g-k*v^2/m
Notice the dependence on m in the acceleration.
For any non-zero velocity, the acceleration will be greater for the heavier object.
This is because there is the same upwards force due to air resistance, but a greater downwards force due to gravity.
@@scottwalker6386 The "action" of drag against the object is not directly proportional to mass.
If you take action to be force, it is not related to mass. If you take it to be acceleration, then it is inversely proportional to mass.
@@jeffreyblack666 Action of F *is* acceleration. And you're correct, the relationship is inversely proportional from the perspective of the acceleration due to gravity, or directly proportional from the perspective of the acceleration due to drag (in the opposite direction)
@@scottwalker6386 Wrong again.
If you are talking about the action of a force, then for gravity the relationship is constant. That is because F=m*g=m*a, so a=g, with no dependence on mass.
It is proportional to mass if you are talking about force instead of acceleration.
For air resistance, it is inversely proportional, because a larger object requires a greater force to accelerate it (or decelerate it).
Being in the opposite direction does not make it directly proportional.
Directly proportional means that if you double the mass you double the result. So that would require a heavier object to be more affected by the air.
Kan, I was going to say, maybe you can make an M shaped balloon apparatus the keep your wedge brick cockpit near the top and less drag.
But rocketa did the trick
I’ve put a bunch of dynamite on an armored seat and literally ricocheted off the top border
Fun fact: the trailmakers sounds barrier is 1234
how about a vehicle that can travel at mach 1 and maintain the sonic boom effect with the cone for an extended amount of time
Did no one else realize that his first attempt was only 2 km away
6:04 kan lose his mind
Let's go
You know you can use gimbal thrusther right?
Adding more weight will make it fall faster as soon as there is air resistance or buoyancy.
You should see if you can break the sound barrier going up with just balloons. If that doesn't work, then start adding thrust.
I think Scrapman already did that one
@@edopronk1303 ah, I'll have to take a look at his channel then.
Can PARTY BALLOONS Break The Sound Barrier? [Trailmakers] another one
Id imagine more mass does help
But only increasing your terminal velocity more cause drag would have less of an effect cause your harder to move
It wouldnt change your acceleration at all though
Sure will. F=ma. It won't affect F, but it'll affect how much F can change the acceleration of the object due to gravity.
If it doesn't change the acceleration, how can it change terminal velocity. Terminal velocity is when acceleration reaches 0. So if the acceleration is the same, terminal velocity has to be.
@@jeffreyblack666 It doesn't affect the acceleration from gravity, it affects the air resistance. The acceleration remains the same from gravity while the air resistance is less effective against a heavier object with the same air resistance. It depends on if you're looking at the acceleration from gravity or just 'acceleration' in general, both can be technically correct.
@@rallok2483 There is no reason to look at just gravity. It goes to a pointless technicality, which doesn't correspond to anything physical.
There is an object which is being acted on by air and gravity. The acceleration of that object is being discussed, and should be considered with both air resistance and gravity.
And that acceleration changes if you change the mass.
There is also no need to put acceleration in quotes like that.
If you replaced all the baloons with gimbal jets the aerodynamics wouldnt be as bad and tou could probably get up there faster
No. Gravitational acceleration is about 9.8m/s^2. You will keep accelerate until drag and acceleration are in equilibrium and them you will just keep on falling at a constant speed but it will not be near the speed of sound.
Trailers physics so don’t argue by real life rules
scrapman just accidentally did this...
Bro's been watching RCE
ASK SCRAPMAN FOR HELP, He can help
Didn't scrapman already do this?
Yeah.. Accidentally
did this in a best creations vid
RCE did this like 1-2 years ago lol
Heh super sonic lawn dart.
Pog
Anyone remember when scrapman did this with a giant lawn dart?…
It´s logical, that it got a bit faster. The game simulates air resistance and when you put more weight behind the space you travel through with gravity, you get a higher terminal velocity.
@kAN Gaming you might have a scammer in your comments
anyone here after scrapman completed this challenge accidentally 😂
by plain falling yes but the thing has to be massive
kan never touched test map skybox???
Hey, can’t you should try legend of Zelda tears of the kingdom it’s basically legend of Zelda meets scrap mechanic
Hello
It's really not that difficult. Inspired by Scrapman's video where he broke the soundbarrier with gimbal jets, I built a simple contraption that uses gimbal jets to go up, brakes the soundbarrier, detaches the gimbal jets and brakes the soundbarrier on the way down.
Scrapman also did this with a giant lawndart contraption.
@@Core-1948 I believe that was one of his workshop videos. And yes, that inspired the falling part of my contraption, allthough mine was a much simpler design.
I don't know if some update changed the physics or if the creator just wanted it to look cool, but it was way bigger than it needed to be.
Makes me nautious watching the climb/fall
7:12 …
Yes you can
what did i just watch
POV: everyone listening on how the balloons work, me realising how sus the first 2 balloons came on.
And btw, this is comment 69 no cap(there is 68 comments right now and this is the 69)
air mines
Didn't scrap man already do this? Not to shoot down your video obviously, a bunch of people do the same things all the time but we already know it's possible.
i really want this game but am poor gamer
scrapman did this 3 years ago
and he also did this recently.ACCIDENTALLY.
@@Damian-cilr2 ik i just pointed it out also you need to calm down a bit
Mass doesn't increase acceleration even with air resistance. It increases terminal velocity, but you hit the ground before terminal velocity was even reached
Acceleration does decrease gradually though, when you're near terminal velocity. So even though he didn't quite reach terminal velocity, just adding a bit more mass would already have been enough to exceed the speed of sound.
@@Nomiswelt Do you mean it decreases over time or with mass difference? Because yeah the acceleration will decrease slower with higher mass but that difference would be negligible
@@laurensholthof What I was trying to say is during free fall all the way up to terminal velocity, the acceleration isn't constantly 9,81m/s² until you reach terminal velocity and then it suddenly jumps to 0m/s². The higher your speed, the more aerodynamics will play a role and decrease acceleration. This is especially noticeable near terminal velocity, as your speed gradually levels off
I think the acceleration of a falling object as a function of its velocity follows a quadratic function (as drag is proportional to velocity squared) which has its maximum at v=0m/s with a=9,81m/s².
"a" (the coefficient of the quadratic term) is negative and directly proportional to the mass of the object.
If you draw this function (y = a*x² + 9,81 with y being acceleration and x being velocity) in GeoGebra or something similar you can alter the "a" in the formula and see how exactly the acceleration changes (remember, "a" is directly proportional to mass).
For a terminal velocity of somewhere around the speed of sound (343m/s) "a" should be about -1*10^(-4).
@@Nomiswelt Yeah ofc, FD =(1/2)ρ*CD*A and if v increases so does FD, but let's say his terminal velocity with m1 (mass on first aircraft) is v1 and his terminal velocity with m2 is v2. Gravitational force will be lower for his first machine, so the drag vector will have the same magnitude as the Fg vector sooner. In m2, at v1, the object isn't at terminal velocity yet but has the same amout of drag as m1 in that moment. Fg is greater with m2 so it will take longer for the resulting vector to become 0N and the acceleration to be 0m/s², but because the drag increase is exponential (v is squared), the closer you get to v1 the further the accelerations will drift apart. Because he hasn't reached terminal velocity, however, could the argument be made that the delta between accelerations is not big enough to cause a sizablr difference in speed at impact. Sorry for the long-winded and confusing text, this was written on my phone
kAN made rods from god and doesn't even know it

The extra weight did help. You accelerated at the same speed, but you continued accelerating at higher speeds for longer
This is the best way to put it. Acceleration is highest at velocity = 0, but the more mass the object has, the slower it will decelerate. i.e., if you have 2 objects with the same coefficient of drag and drag cross-section (and thus same aerodynamic drag), but different masses (and hence different terminal velocities), which will reach the terminal velocity of the less massive object first? The more massive object. The more massive object will in fact decelerate slower. It'll only become appreciable at pretty high speeds, though.
No, they accelerated at a greater rate. If they accelerated at the same speed they would reach terminal velocity at the same speed.
The only way to exceed the terminal velocity of the original is by having the acceleration be different (so it is not 0 at the terminal velocity of the lighter object).
Yoooo
Adding weight to it probably would have made it fall faster even in real life like for example if you drop a feather on one side and a 50 pound weight on another side the weight will fall faster and hit the ground harder and faster than the feather because of weight now if you added 10 pounds to a feather then it would fall faster😂
That's not because of weight but because of aerodynamics. If you have a metal cube and a hollow metal cube of same dimension, both will fall the same speed
Yes the feather just has a lot more drag, if it was in a vacuum they would fall the same speed.
@@xelspeth it does make a difference when auerodynamics are significant. If you drop your metal cube and hollow metal cube from high up enough, the hollow one will hit the ground later. You are correct in a vacuum tho
@@xelspeth It is because of both.
If you have a solid metal cube and a hollow metal cube of the same dimensions, and drop them in an atmosphere (or fluid) the hollow metal cube will fall slower as soon as air resistance becomes significant.
You can try this with an alfoil cube, vs a solid block of aluminium
I didnt say a vacuum or a hallow cube and even if there was a hallow cube and a solid one, they both might be close to the same speed if you drop them but the heavier one will allways be slightly faster because thats just how gravity works
You have no idea how physics works

kAN, as a fellow engineer, I am sure you know the FBD for terminal velocity. F_g=F_d so mass affects terminal velocity, but not the acceleration, assuming normal physics. As you said, who knows with a video game.
As terminal velocity is when acceleration is 0, it is impossible to affect terminal velocity of a falling object without also affecting accleration.
interestingly im pretty sure there shouldnt be a boom if you are just falling silently
Bullets make noise and they're just flying through the air
