** **
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 would say that it is traveling faster because the force of gravity would be positive as it travels down whereas it was negative as it traveled up.
• What, if anything, is different in your answer if air resistance is present? Give your best explanation.
answer/question/discussion:
I would say that it would travel about the same because air resistance could be negligible
