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: ->->->->->->->->->->->-> n:
The force of the air resistance will increase
#$&*
What happens to the net force acting on it?
answer/question/discussion: ->->->->->->->->->->->-> n:
The force of air resistance will act in the direction opposite of motion (gravitational force) and will decrease the net force as velocity increases.
#$&*
What happens to its acceleration?
answer/question/discussion: ->->->->->->->->->->->-> n:
At `dt = 0, acceleration will equal that of the gravitational force. As the velocity increases, air resistance will cause acceleration to be less.
#$&*
If it dropped from a much higher point, what would happen to the net force and the acceleration?
answer/question/discussion: ->->->->->->->->->->->-> n:
The object’s velocity would continue to decrease as air resistance increases. At some point, I think the force exerted on the object by gravity and the air resistance would be the same and acceleration would be zero.
