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 traveling at the same speed as it was when it was released. The is due to the fact that gravity is a conservative force.

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

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

 The ball will be traveling at a lower speed than when it was released because the ball loses some energy because it is being resisted by air.
