He's really good with the exception of 1 nitpicky thing: reentry heat is only something like 5% from friction (not sure of the actual number but it's low). Most of it is due to ram heating, ie the air in front of the capsule getting rapidly compressed and therefore heating up (like when you let pressurised deodorant out of a can and it gets cold, but in reverse) :)

The fireball around objects entering orbit is mostly caused by the air ahead of you heating up due to compression. This is why all reentry vehicles are flat and heat shielded facing the ground (including the challenger). If the fireball was coming from friction, only covering 10% of the surface area wouldn't make much of a difference.

@@Cyberboi well you see that wasn't the entire story. Me and a bunch of friends had rented mountain bikes to then fuck around with for a day, so we went up the nearest mountain (since we couldn't find any proper trails that weren't actual downhill trails). My friends gave up a third of the way up, and told me that if I really wanted to make it to the top I could go on alone, so naturally I disregarded their wishes and did so. Once at the top I started descending again while braking all the time, until I got to a spot like 200 meters beyond where I had left my friends. I found one of my other friends who had just decided to go a bit farther up himself. So we then descended together to where the remaining friend was sitting, and when we stopped my friend held his hand a bit away from the brake disc on his rear wheel and concluded it was hot, so I wanted to check on mine but somehow my brain decided it would be best to do this by grabbing the disc rather than holding my hand a bit away from it and feeling the radiating heat. So all in all it left me with a cool story which somewhat redeemed the bad experience.

[@Gentleman...Driver]

@@Seagull780 Works with cars as well. I saw a very unexperienced dutch guy with his family in a Volkswagen T5 in front of me. He constantly braked all the way down the mountain. It was a 2000 meter high mountain in the french alps. I honked and flashed my lights at him, but he didnt understand of course. So I tried to overtake and signal him, but that didnt work also. He simply thought I was an asshole and I wanted to do him some harm. As we were finally down I overtook him and got on my brakes. We slowed down until we stopped. Then I saw that his brakes were already on fire. I had an extinguisher with me. At the end he understood what I wanted from him all the time. When you drive down a mountain, use a low gear and let the engine do the breaking for you. Just brake right in front of the corner. Let them cool of as much as possible in between.

[@umad42]

@@Gentleman...Driver Generally just keeping it out of overdrive if it's an auto, or the highest gear in your manual, is enough to keep you slowed down. However, since people are lazy, modern vehicles do well enough if you just use the brakes while following mechanic's input on when to replace parts at regular services, because modern rotors generally are advanced enough alloys that they do not want to hold onto the heat you are generating with the friction, and can cool off well enough so long as you aren't dragging on them for 40+ minutes, or aren't constantly slowing down from high rates of speed.

18:00 just FYI the most of the heat generated during reentry is NOT caused by friction but rather by something called ram heating. As the heat shield passes through the atmosphere the speed of the craft compresses the air in front of it into incandescent temperatures. Most of the heat is generated in this manner. If it wasn't for the shock layer the friction would likely be greater. (Although it is easy to see why many people would think it is mostly via friction)

[@pablocs3311]

I checked the comments to not comment twice on the subject. Correct, most heat is caused by adiabatic compression of the gases in the atmosphere. But the vehicle's kinetic energy is ultimately lost to friction with the atmosphere (viscosity)

[@EchoNovemberDelter]

SHUT UP KEVIN

[@derpkube]

This can be compared to ramming a car at highway speeds into a crowd of old people. If I were driving the car any slower, then they would have time to move out of the way. However, due to my extreme speed, the old people cannot move out of the way, and are killed instantly. If I keep on driving through the crowd, not only would I slow down, I would also accumulate a pile of now-dead old people at the front of the car, keeping my bumper safe from any more damage. This is comparable to the shock layer and deceleration a spacecraft experiences during re-entry.

15:20 Im a physics student, lemme explain: When an object is in motion at some distance away from the center, there is a centripetal force, and centripetal literally means "center seeking". The centripetal force in question is exhibited on the mass pulling toward the center of the circle. Think of an arrow that starts at the mass and points toward the center, that's centripetal force. The problem is that in order for an object to spin in a circle, it needs to be connected to the center by something like a string. Try and try all you will, you can't get an object in air to spin in a circle continuously without it being connected to the center. So what is centrifugal force? It's whats known as a felt force, and is actually a result of angular (or rotational) velocity. Think of yourself on a train that's moving. You'd fall over because you're "feeling" a force acting on you, when in reality, nothing pushed you over, the train just had some velocity to it. Now if there were a wall behind you, the same thing would happen, except the wall is pushing back on you, keeping you from falling. This feeling, when you're spinning, is what we call the "centrifugal force".

[@ianrzep9011]

Wow

[@tibsky]

sHUT UP KEVIN still interesting lol

[@rowandoyle7]

Yup, it's essentially a felt force of an object's inertia

[@Zwaolin]

Or in other words a felt force is the result of all objects with a mass having inertia. Or even simpler, objects don't want to change direction. In order to spin in a circle, the object has to change direction all the time towards the center of the circle. The not wanting to change direction is therefore a felt force in the opposite direction, aka away from the center of the circle.

17:48 Actually, it isn't air friction which heats spacecraft, but rather air compression. At those heights there isn't enough air for friction to matter, but you're moving so fast that Air doesn't have enough time to move away. And as the ideal gas law says, compressing a gas raises its temperature, thus, the ship gets hot. TL;DR: Air compression, not air friction.

Was gonna comment this. Air doesn’t really have appreciable friction in the traditional sense. The molecules do have some friction as they rub past the solid, but the resistance that air has comes from pushing the particles out of the way, not them rubbing against you.

[@angusmacdougall9732]

Lmao, the one fact that Kevin got recognition for, he actually got wrong. Most of the heating from reentry is from adiabatic compression, not friction. This is when you run into air very fast and it doesn't have time to get out of the way, so instead gets squashed. This makes it very angry, so it throws fire at you.

[@nethascotx24]

Accurate

[@jakejones8225]

What's the difference between adiabatic compression and friction? (Not that I'm testing you I just genuinely am interested)

[@nethascotx24]

Jake Jones If I remember correctly, the adiabatic compression has the gas accumulate at the front end of the vessel. Due to gas laws, this causes them to heat up. Eventually it turns to plasma, reaching insane levels of heat. In friction, the air passes alongside. It requires the movement of air in contact with the vessel, and it won’t heat up the vessel at much. It is still very much at play but most heat shielding is for compression. Hope I solved your doubt!

[@angusmacdougall9732]

@@nethascotx24 Exactly, for an example of friction, consider a rotating cylinder. It does not displace any air, so there is no adiabatic compression, but it will still produce some heat due to the air rubbing against its surface. Conversely, though it won't remove friction, you can amplify the effects of adiabatic compression by trapping the air, e.g. inside a piston.

15:17 Challenge accepted! Centrifugal force is often described as a fictitious or pseudo force in physics. It appears in a rotating reference frame, where it acts outward on objects moving in a circle, giving the sensation of an outward force from the center of rotation. In an inertial (non-rotating) reference frame, what we actually observe is the effect of inertia. Objects tend to move in a straight line due to their inertia, but when constrained to a circular path (e.g., by a string or a gravitational force), they experience a centripetal force pulling them towards the center of the circle. This centripetal force is responsible for the circular motion. In the rotating reference frame, however, the laws of motion must account for the rotational motion. To explain why an object does not simply fly outward, we introduce the concept of centrifugal force, which appears to act outward, balancing the inward centripetal force and maintaining the circular motion from that perspective. Therefore, while centrifugal force is not an actual force in the inertial frame of reference, it is a useful concept in a rotating frame of reference to explain the apparent outward force experienced by objects.

[@terrotron8742]

@@jimmer828 pretty much. space craft move faster than the speed of sound most of the time, so instead of the air molecule being able to move out of the way, they're forced out of the way. so you create a shockwave where the air molecules compress and then at a certain point that shockwave is pushed through resulting in a sonic boom. by moving at such high speeds and forcing the air molecules around the aircraft, they rub more and create friction, resulting in aircraft such as the SR-71 which travelled 3x the speed of sound to get as hot as 450 - 950 degrees celcius in flight. same kinda thing happens on re-entry. another way to think about it is a speed boat moving through the water so fast that the friction of the water molecules on the boat's hull begins to generate steam, though that's slightly different but a simple kind of idea.

[@terrotron8742]

@@dirtypure2023 you're both pretty much correct. i've written a much longer explanation on it but the short end of it is that it's just complicated friction. you move so fast it builds up and then can't "stick" anymore so it gets blown away, hence why you get sonic booms.

[@owenzook5261]

Though I am late to the party, as a physics major (BA so I care less) I wish to explain centrifugal force and not be repeatedly shot by a neon meme frog. A way to think about centrifugal force is the idea of equal and opposite reactions (mentioned previously in the video); however, with a slight catch. The centrifugal force is more akind to the force you would feel while spinning than a force outright. The force on the string caused by the spinning is due to the tautness of the rope as you pull it outward by spinning it. Imagine being in one of those carnival rides, like a teacup, spinning and pushing you outward towards the seats. Though not a string, the idea still remains as you are pushed outwards, making it seem as if there is a force pushing you away from the center, but in reality it is your body acting coarsely to the force being directed inward to the center of the spinning axel. This is all caused by the viewers reference frame really, as they seem to be pushed away, but in reality are moving due to a force pushing in and basically being yeeted out of the frame. Another way to think about that is one of those playground marygorounds you try to yeet people off and cause the most injurie. Is this explanation correct: mostly. Do I care: slightly. Am I still about to be shot by a neon green meme frog: probably.
