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: ->->->->->->->->->->->-> :
After looking through the notes and the video clips, I see that the air resistance is proportional to the velocity. If I understand what I saw correctly, I believe that as the speed increase, the air resistance decreases.

•What happens to the net force acting on it?
answer/question/discussion: ->->->->->->->->->->->-> :
I believe the net force would increase.

•What happens to its acceleration?
answer/question/discussion: ->->->->->->->->->->->-> :
Well if the Fnet increases, the acceleration would have to increase as well, as the time required would decrease.

•If it dropped from a much higher point, what would happen to the net force and the acceleration?
answer/question/discussion: ->->->->->->->->->->->-> :
I believe the Fnet and acceleration would decrease since the time it would take to fall to the ground would increase.
