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: ->->->->->->->->->->->-> :
the force of the air resistance would increase as the speed of the object increases. So the force of air resistance would increase as the object initially at rest falls.

• What happens to the net force acting on it?
answer/question/discussion: ->->->->->->->->->->->-> :
gravitational force would act in the direction of motion, air resistance acts opposed to motion. So the increasing air resistance would decrease the net force. Net force would be downward but decreasing as velocity increases.

• What happens to its acceleration?
answer/question/discussion: ->->->->->->->->->->->-> :
acceleration would decrease as the object falls because of the increasing air resistance.

• If it dropped from a much higher point, what would happen to the net force and the acceleration?
answer/question/discussion: ->->->->->->->->->->->-> :
the object would still keep speeding up but at a lesser rate.
