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: ->->->->->->->->->->->-> :
Air resistance is proportinal to the change in velocity. Therefore, the air resistance would increases as the speed incrases.
#$&*
What happens to the net force acting on it?
answer/question/discussion: ->->->->->->->->->->->-> :
Fnet = m * a
The net force would decrease because air resistance increases.
#$&*
What happens to its acceleration?
answer/question/discussion: ->->->->->->->->->->->-> :
The paper's acceleration would decrease. As the air resistance increased and the paper slowed down, the acceleration would slow down.
#$&*
If it dropped from a much higher point, what would happen to the net force and the acceleration?
answer/question/discussion: ->->->->->->->->->->->-> :
The net force and acceleration would approach 0. The air resistance would eventually reach the weight of the falling object.
