00:00So, a plane that is not accelerating is a neutral force balance.
00:05You have the force of gravity, you have the lift force of the wings, then you've got the
00:11force of the thrusting device, the propeller or turbine or whatever it is, and you've got
00:18the resistance force of the air.
00:20Now, the higher you go, the lower the air resistance is.
00:24Air density drops exponentially, but drag increases with the square.
00:29Exponential beats a square.
00:30The higher you go, the faster you will go for the same amount of energy.
00:33I'm too stupid for this conversation.
