Physics Of Bowling

The ball motion shown is typical for a right-handed bowler. For a left-handed bowler the motion is simply "mirrored" so that the ball curves towards the left gutter instead of the right gutter, before hitting the pins. The ball begins rolling with a rotation speed (angular velocity) of w o and a linear velocity V o.
