that is the CHANGE IN MOMENTUM OF THE BALL kallog.

the ball still presents the same force to the wall.
the force that is its mass * velocity.
or your used to using p=mv
the momentum that is its mass * velocity

just like the mass still presents the same force to
the U turns.



its the elastisity of the ball that allows it to bounce
off the wall.

like compressing a spring.
the ball is compressed like a spring because of its
momentum.
