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 should be traveling the same speed due to conservation of energy PE + KE = 0

What, if anything, is different in your answer if air resistance is present? Give your best explanation.

answer/question/discussion: I imagine it would be the same because air resistance would be a constant resisting force during upward and downward motion.
