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 be traveling faster. When the ball was tossed upwards, it had the force of gravity working against it. It was pulling it down even though the ball was tossed up. On the way back down, the gravity works in the balls favor bringing it back down to it’s starting position.

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

answer/question/discussion: ->->->->->->->->->->->-> :

If you take into account air resistance, the problem will be the same. When you throw the ball upwards , it not only has the forces of gravity pulling on it, but also air resistance slowing its speed upwards. On the way back down, the ball is being affected by gravity as well as air resistance .
