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: ->->->->->->->->->->->-> :

Magnitude gets larger.

• What happens to the net force acting on it?

answer/question/discussion: ->->->->->->->->->->->-> :

It should decrease because Net = Gravity - Air resistance

#$&*

• What happens to its acceleration?

answer/question/discussion: ->->->->->->->->->->->-> :

Decreases as the force decreases.

#$&*

• If it dropped from a much higher point, what would happen to the net force and the acceleration?

answer/question/discussion: ->->->->->->->->->->->-> :

Depending on the height it may get to the point where resistance = weight and then acceleration would be zero from this point down.
