Abstract
Golf ball with a novel combination of spin rate, lift coefficient, drag coefficients, and optionally moment of intertia: a golf ball with a low spin rate, a high lift coefficient, a low drag coefficient, and optionally a high moment of inertia; and a golf ball with a high spin rate, a low lift coefficient, a low drag coefficient, and optionally a low moment of inertia.
Claims21
A golf ball comprising a core and cover, wherein the golf ball comprises a moment of inertia of about 0.46 oz/in2 or greater, the lift coefficient is greater than about 0.20, the drag coefficient is less than about 0.22 at a Reynolds Number of about 145000.
11-20. (canceled)
A golf ball comprising a core and cover, wherein the golf ball comprises a moment of inertia of about 0.48 oz/in2 or greater, the lift coefficient is greater than about 0.20, and the drag coefficient is less than about 0.22 at a Reynolds Number of about 145000.
