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 it speeds up the more air resistance it will encounter.
• What happens to the net force acting on it?
answer/question/discussion: ->->->->->->->->->->->-> :
The higher up the wad of paper the more force (gravity) will be pulling down on it.
• What happens to its acceleration?
answer/question/discussion: ->->->->->->->->->->->-> :
The longer the wad of paper falls the faster the acceleration will be.
The longer the wad of paper falls the faster the acceleration it will have.
• If it dropped from a much higher point, what would happen to the net force and the acceleration?
answer/question/discussion: ->->->->->->->->->->->-> :
The acceleration will be faster and the net force will be greater.
