摘要： A hollow golf ball comprising a hollow core and a cover layer that possesses good shot feel, an increased moment of inertia, and a high launch angle at the time of hitting. Immediately after impact, the hollow golf ball has a small spin amount. The specific hollow core reduces the rate of spin dumping between the ascending and descending of the ball, which results in increased flight distance. The hollow golf ball has a hollow core and a cover layer formed on the core, wherein the hollow core is composed of a hollow portion having a diameter of 5 to 30 mm and a core outer layer portion surrounding said hollow portion.

摘要： By bringing a golf ball into collision with a collisional plate and measuring a coefficient of dynamic friction at this collision, contact force at the time of collision between an actual golf club and the golf ball is analyzed and spin rate of the golf ball is estimated. This invention provides a method for measuring a coefficient of dynamic friction between a golf ball and a collisional plate when the golf ball collides with the collisional plate disposed aslant at a predetermined angle with respect to a flying direction of the golf ball. The method includes concurrently obtaining a time function Fn(t) of contact force in the direction perpendicular to the collisional plate, and a time function Ft(t) of contact force in the direction parallel with the collisional plate; and determining as a coefficient of dynamic friction, a maximum value of a time function M(t) of ratio between Fn(t) and Ft(t) represented by M(t)=Ft(t)/Fn(t).
