<p>A golf ball is provided having a controlled moment of inertia. The golf ball (10) includes a core defining at least one hollow channel (16a-e). At least one movable weight (17) is located within each hollow channel.The end of the hollow channel at the outer edge of the core is closed with a plug (19). The movable weight and plug may each further include a magnet or the hollow channel may include a placement member such as a spring (18) to control the movement of the weight. When the present golf ball is struck, the spin rate forces the weights to move from the interior of the core outwardly towards the outer edge of the core, thereby varying the moment of inertia of the golf ball. The method of manufacturing the present golf ball is also provided.</p> |
