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 drops, the speed increases and thus means that the air resistance increases as well. Only until the downward velocity and the resistance balance out until velocity is constant.

• What happens to the net force acting on it?
answer/question/discussion: ->->->->->->->->->->->-> :
The force acting on the paper will balance out because velocity will be constant and there are no other forces to increase to speed.

• What happens to its acceleration?
answer/question/discussion: ->->->->->->->->->->->-> :
The paper will accelerate until it reaches a speed where acceleration will stop and the velocity will be constant.

• If it dropped from a much higher point, what would happen to the net force and the acceleration?
answer/question/discussion: ->->->->->->->->->->->-> :
If the paper is dropped from a higher point, the max velocity will reach its speed at a higher point. The terminal velocity will be the same as the lower drop because the mass is the same and the same velocity is attained before hitting the ground. Thus the acceleration will be the same.
