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?

Faster

What, if anything, is different in your answer if air resistance is present? Give your best explanation.
answer/question/discussion: ->->->->->->->->->->->-> :
I think air resistance would make it slower coming back down. for instance a paper airplane would certain slow down as it came back down.

Be sure to check the discussion at the link. The speed when returning will be equal to original speed, in the case where air resistance is absent.
