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 velocity should be the same at the ending position that it was at the start position. The only difference is that the ending velocity will be negative because moving up is the positive direction.

• What, if anything, is different in your answer if air resistance is present? Give your best explanation.
answer/question/discussion: ->->->->->->->->->->->-> :
The velocity would not be as fast at the ending position if you take into account air resistance. This is because the resistance does not allow the object to speed up as quickly, so the final velocity will be less than the initial velocity.
Right; also, the object doesn't rise as high.
