A golf ball has one or more grooves in the ball surface. When the ball is initially struck by a golf club at an oblique angle the ball can have an undesired side spin. Each groove in the ball surface interacts with the air stream to absorb some of the side spin energy. The grooves act like miniature turbine blades, or the vanes on an in-flight arrow, to decelerate side spin velocity so as to reduce the tendency of the ball to hook or slice. |
