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: probably slower, however it would depend on how fast the ball was rising before it came back down
What, if anything, is different in your answer if air resistance is present? Give your best explanation.
answer/question/discussion: there would be no difference, the air resistence will be the same in both directions
