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 should have little affect on the wad of paper, since the problem states the air was still.

What happens to the net force acting on it?
answer/question/discussion: ->->->->->->->->->->->-> :
The net force is equal to mass * acceleration. Neither the mass or acceleration change on the object, so it will stay the same.
If the air is still, then the accelerating object is moving faster and faster with respect to the air.
#$&*
What happens to its acceleration?
answer/question/discussion: ->->->->->->->->->->->-> :
The acceleration stays the same.
#$&*
If it dropped from a much higher point, what would happen to the net force and the acceleration?
answer/question/discussion: ->->->->->->->->->->->-> :
The mass and acceleration will not change, so neither will the net force.
