It will slow up the rise on the ball, but not stop it immediately from rising. Think about it. It is not that difficult.
slowing down a rise=starting a drop
slowing down a forward motion=deceleration
both are a force in the opposite direction of motion and will eventually cause a reversal of direction if continually applied.
the trick here is that you are dealing with a derivative (rate of change) of a quantity (rise or velocity) and not the actual quantity itself (rise/velocity). the derivative goes negative (drops/slows down) before the vector of the quantity goes negative.
you must have been a business major and taken that "pretty people" physics. Us true geeks took the hard stuff.
