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: ->->->->->->->->->->->-> :
I think that the ball will be traveling faster. When it is first released is starts from zero and gradually speeds up. When it reaches the maximum height it stops briefly (you don’t even notice) and then accelerates as it falls, so I believe it will be going faster.

• What, if anything, is different in your answer if air resistance is present? Give your best explanation.
answer/question/discussion: ->->->->->->->->->->->-> :
If air resistance were present, I think my previous answer would still be the same. The difference would be that the rates at which the object accelerates would be slower.
