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 will slow it down and air resistance increases also
#$&*
What happens to the net force acting on it?
answer/question/discussion: ->->->->->->->->->->->-> :
the force increases
#$&*
@&
If the net force increases, the acceleraiton increases.
At the beginning air resistance is zero, the net force is equal to the weight and the acceleration is 9.8 m/s^2 downward. If the nat force increases, then the acceleration will exceed 9.8 m/s^2 and the object will speed up faster than a freely falling object in the absence of air resistance.
*@
What happens to its acceleration?
answer/question/discussion: ->->->->->->->->->->->-> :
It accelerates at first but accel slows
#$&*
@&
Acceleration can increase or decrease, but it doesn't slow.
To say that acceleration slows tends to confuse the meanings of velocity and acceleration.
*@
If it dropped from a much higher point, what would happen to the net force and the acceleration?
answer/question/discussion: ->->->->->->->->->->->-> :
It may reach terminal velocity at which point it stops accelerating

Pretty good, bu tbe sure to check my notes.
