ABSTRACT:
A bowling ball comprises a core, a cover surrounding the core, and a weighting rod for increasing the weight density of the bowling ball along the spin axis, thereby reducing the bowling balls moment of inertia about the spin axis. To modify the trajectory of the ball's hook, or arc, on the bowling alley lane, the rod's weight may be offset so that one side of the bowling ball is heavier than the other side. The biased nature of the weight causes the bowling ball to develop precession, and improve the hooking nature of the trajectory.
