"Terminal velocity" is the maximum velocity of a body as it falls through air. Mathematically, the velocity at ground increases with the starting height, but beyond a certain height the increase is negligible.
That is really not true, due to the fact that the atmosphere gets less dense at higher altitudes.
Jumping out of a plane at 12,000 feet, an average-sized man will reach a terminal velocity of between 100 and 120 mph in about 12 seconds.
If the same man jumps out a 180,000 feet, his terminal velocity would be supersonic.
Yeah, you do not even need to be that extreme, the difference is noticeable when you jump from 12,500 than if you jump from 18,000ft you climb the hill faster and you accelerate to a higher speed and your terminal velocity decreases as you drop - the "climbing the hill" is more violent at 18,000 ft , noticeably so.
I am talking from experience here.
