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 same speed.

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

answer/question/discussion: ->->->->->->->->->->->-> : I think it will probably be a fairly similar speed again, I have no reason to believe that air resistance isn’t constant both when rising and falling.
