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: ->->->->->->->->->->->-> scussion:
If air resistance is proportional to velocity, it will encounter greater resistance with greater speed.
#$&*
What happens to the net force acting on it?
answer/question/discussion: ->->->->->->->->->->->-> scussion:
Since air resistance is acting opposite the direction of motion and opposite gravity (the primary force), then the net force will decrease.
#$&*
What happens to its acceleration?
answer/question/discussion: ->->->->->->->->->->->-> scussion:
As a result of the decreased force, acceleration will decrease. Velocity is still increasing but a slower rate.
#$&*
If it dropped from a much higher point, what would happen to the net force and the acceleration?
answer/question/discussion: ->->->->->->->->->->->-> scussion:
Eventually the net force and acceleration would reach zero and velocity would be constant.
