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 air resistance it encounters is proportinal the change in velocity, so when the wad speeds up, air resistance increases
#$&*
What happens to the net force acting on it?
answer/question/discussion: ->->->->->->->->->->->-> :
The net force acting on the wad of paper increases because of potential energy, the further the drop, the more the force of the wad in the negative direction
#$&*
What happens to its acceleration?
answer/question/discussion: ->->->->->->->->->->->-> :
the acceleration is gravity, but once air resitance comes into affect the wad will begin to slow down and acceleration will decreasestays constant
#$&*
If it dropped from a much higher point, what would happen to the net force and the acceleration?
answer/question/discussion: ->->->->->->->->->->->-> :
the net force will continue to increase and acceleration will continue to decrease, balancing each other other. net force and acceleration will be constant and unchanging
