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

I assume the air resistance still occurs but it is more easily overcome as the wad speeds up.

What happens to the net force acting on it?

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

I believe the force acting on the wad remains constant since it is gravity.

#$&*

What happens to its acceleration?

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

The acceleration is that due to gravity--9.8m/s^2 so the object will continue to accelerate at this rate as it falls.

#$&*

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

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

I believe the force and acceleration will still remain constant, the velocity will change though.
