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 will be faster than when it was released. When tossed up, it has an initial velocity that is working against the -9.8 m/s/s acceleration of gravity. When it comes back down, it has only gravity working with no upward velocity countering it.

• What, if anything, is different in your answer if air resistance is present? Give your best explanation.
answer/question/discussion: ->->->->->->->->->->->-> :
Air resistance would slow the ball down in both directions. Therefore, the ball would still be faster falling than when it was tossed up.
