As we discussed before the axis of
rotation is very important and more specifically, it is
important to the motion of the ball. The location of the
PAP effects the Precession of the ball which is the change
in the central axis as the ball rotates around.

In general the more precession there is the more friction
there is and this causes a greater hook in the ball. The
greater friction is caused from the rocking that
precession creates. As the ball rocks more of its surface
area makes contact with the lane distributing the oil out
more so the ball is less slick. A good bowler can use this
information to throw the ball specifically to create
either more or less precession and therefore control the
hook of their ball. On the other hand the bowler must also
understand that the more friction that there is between
the ball and the lane the more speed the ball will lose
before it hits the pins. The smaller velocity of the
ball directly effects the moment that ball has
before it hits the pins. We know this by the definition of
momentum as P=mv. Understanding the physics in how a ball
is thrown and how it effects the motion of the ball is a
great advantage in the game of bowling and widen a
bowler's range of motion.
