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: ->->->->->->->->->->->-> :
It will traveling the same speed when it reaches its original position as when it was released, because the KE will be equal and opposite of the gravitational PE.

• What, if anything, is different in your answer if air resistance is present? Give your best explanation.
answer/question/discussion: ->->->->->->->->->->->-> :
If air resistance is present, then when the ball is tossed vertically upward it will force the ball down, and when the ball is coming down it will force the ball up. So, air resistance is acting in the opposite direction of motion.
