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: ->->->->->->->->->->->-> :
Air resistance increases as speed increases.

• What happens to the net force acting on it?
answer/question/discussion: ->->->->->->->->->->->-> :
Since the objects mass and gravity do not change, force due to gravity stay the same. Since air resistance increases, the net force continues to be downward but it is decreasing.

• What happens to its acceleration?
answer/question/discussion: ->->->->->->->->->->->-> :
Since the mass stays the same and the net force is decreasing, the acceleration is decreasing.

• If it dropped from a much higher point, what would happen to the net force and the acceleration?
answer/question/discussion: ->->->->->->->->->->->-> :
The net force, and therefore acceleration would continue to decrease until the object stopped accelerating. At this point it would have reached terminal velocity.
