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:

When you toss the ball into the air, gravity is gradually slowing it down. On the coming down side, gravity is speeding the ball up. Because the time and distant traveled is the same going up and down, we know the intial velocity would be the same as the final velocity. The speed would then be the same as when released.

What, if anything, is different in your answer if air resistance is present? Give your best explanation.

answer/question/discussion:

If you included air resistance, the things that would change are the top height of the ball and the time between. Air resistance would be the exact same going up as going down. The answer to part 1 would still remain unchanged. The differences come in overall height and time.
