Statistically bowlers that throw a curved ball have much higher
scores than
bowlers that throw a straight ball. How is the curve created
though and why
does it create a higher average bowling score?
The curve of a ball is created by a couple different things. As
discussed before
the friction between the lane and the ball is one factor that
contributes to the
curve. As the ball moves the friction causes the angular
velocity vector to
change. As all of the motion of sliding goes away due to the
opposite force of
friction, the rolling velocity is all that is left. if this is
pointing toward the inside
of the lane as it should be, the ball will proceed to curve
inward.

The weight inside of the bowling ball can also effect
its curve. By offsetting the
weight to be uneven is creates a higher precession when the ball
is thrown.
Most balls are drilled for your fingers in a certain orientation
to the weight
based on the pin that can be sen from the surface. This will
create maximum
curve potential.
The reasoning behind why throwing a ball at a curve increases
a bowler's score has to do with the angle at which the pins are
hit. It is difficult
to hit the pins at the right angle needed to knock all the pins
down with a
straight ball.
