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 of paper speeds up, the air resistance increases.

• What happens to the net force acting on it?

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

If the air resistance is increasing, the net force is increasing. Also, gravity is pulling at 9.8m/s^2 on the wad of paper.

• What happens to its acceleration?

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

The acceleration of the object increases as the distance increases due to gravity.

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

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

I’m not sure, but I think that if the object was dropped from a higher point, it would have a greater net force and acceleration than before because it is traveling a longer distance for a longer amount of time.

The increasing air resistance decreases the magnitude of the net force and therefore the acceleration.
