So, yes and no. Acceleration due to gravity impacts all objects equally. With no air resistance, on earth, everything speeds up at 9.8m/s/s. But, that "no air resistance" is a big asterisk. This is why, say, parachutes work. It's also how we get terminal velocity. Often misinterpreted as "how fast you'd have to go to die from a fall" it's actually "how fast you need to go before the drag from your air resistance is a force greater than or equal to gravity"
Right. That all makes sense. So the air resistance is what is also causing it to heat up. I still don’t see why a person wouldn’t do that.
So, multiple options here. Skydivers regularly hit terminal velocity, as fast as they'll go in atmosphere, before pulling their chutes. At these speeds, heat from friction isn't enough to worry about. Once again though, if you're coming down from space, that "in atmosphere" asterisk goes away. If you're dropping from a satellite, you're going at speeds necessary to orbit, and you don't have anything slowing you down until you hit the atmosphere. Suddenly your terminal velocity is way lower than infinity, and the friction you're feeling from the atmosphere is INTENSE, rapidly turning that speed into heat
Alight cool. All basically what I figured. Thanks!
