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: ->->->->->->->->->->->-> :
The air resistance it encounters is proportional the change in velocity, so when the wad speeds up, air resistance increases
#$&*
• What happens to the net force acting on it?
answer/question/discussion: ->->->->->->->->->->->-> :
It stays the same as air resistance changes.

• What happens to its acceleration?
answer/question/discussion: ->->->->->->->->->->->-> :
Its acceleration will decrease in magnitude, but acceleration won't change direction.
#$&*
• If it dropped from a much higher point, what would happen to the net force and the acceleration?
answer/question/discussion: ->->->->->->->->->->->-> :
If net force increases then so does acceleration. But acceleration does decrease in magnitude.
