Seed quetsion 23.1
A wad of paper is dropped from a second-story balcony and falls through still air to the ground.
As it speeds up, what happens to the air resistance it encounters?
answer/question/discussion: ->->->->->->->->->->->-> :
If a wad of paper is dropped from a second-story balcony and falls through still air to the ground as it speeds up the air resistance would be against the speed of the paper wad so it would act to slow the speed. The wad of paper would fall straight down since the air is still and would not move in the horixontal direction.

What happens to the net force acting on it?
answer/question/discussion: ->->->->->->->->->->->-> :
The net force acting on the paper wad as it falls would be decreased by the force of air resistance acting against the motion of the paper wad in the opposite direction.
#$&*
What happens to its acceleration?
answer/question/discussion: ->->->->->->->->->->->-> :
The acceleration of the paper wad would slow due to air resistance.
#$&*
If it dropped from a much higher point, what would happen to the net force and the acceleration?
answer/question/discussion: ->->->->->->->->->->->-> :
I think that the net force would increase, but the acceleration would stay at a constant with gravity.
