seed 21.1
A ball is tossed vertically upward and caught at the position from which it was released.
Ignoring air resistance will the ball at the instant it reaches its original position be traveling faster, slower, or at the same speed as it was when released?
answer/question/discussion: ->->->->->->->->->->->-> :
The ball will be traveling faster when it comes back down as to when it went up. As it goes up gravity is doing work on the ball in the opposite direction once it is released, as it comes back down gravity is working with the ball increasing its velocity on the way back to the original position.

What, if anything, is different in your answer if air resistance is present? Give your best explanation.
answer/question/discussion: ->->->->->->->->->->->-> :
It air resistance is present on the way down this will tend to slow the velocity as it comes back down.
