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: ->->->->->->->->->->->-> :
As the wad of paper speeds up the resistance gets smaller, or the paper can overcome the air resistance more and more.
check yourself on this one

• What happens to the net force acting on it?
answer/question/discussion: ->->->->->->->->->->->-> :
I think that the net force that is acting on the paper, which is the air resistance, will decrease as the paper drops.
#$&*
• What happens to its acceleration?
answer/question/discussion: ->->->->->->->->->->->-> :
The acceleration of the paper increases as it drops farther, because it gets faster and faster.
#$&*
• If it dropped from a much higher point, what would happen to the net force and the acceleration?
answer/question/discussion: ->->->->->->->->->->->-> :
The acceleration would increase even more and the net force acting on the paper would decrease even more.
