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

If the object speeds up then I think it would be able to overcome more of the air resistance that it encounters.

• What happens to the net force acting on it?

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

If F= m*a then I think that the net force acting on the object will increase. I think this because if our acceleration is increasing and our mass remains the same that the force has ton increase as a result of an increase in acceleration.

• What happens to its acceleration?

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

I think that the greater the distance the object has to fall that the acceleration will continue to increase.

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

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

#$&*

If dropped from an even higher point then I think the acceleration and net force would still continue to increase.

The velocity of the falling object increases. However the acceleration of gravity is constant at 9.8 m/s^2. That acceleration doesn't increase by virtue of increasing velocity. If gravity is the only force acting on the object, its acceleration remains constant.
