Why multilayer golf balls spin less off the tee and more around the greens?
Why do new multi layer balls used on tour spin less than the old tour balls off the driver but spin the same as the old wound balls off the wedge? Ryan Dees, Gainesville, Fla.
During the collision between the driver and the ball (which lasts for less than half a millisecond, 200 times faster than you can blink your eye), there’s an average force of 1,500 pounds being applied to the ball. This violent collision compresses the ball to about two-thirds of its diameter. The cover thickness is less than 3 percent of the size of the ball but doesn’t much influence the outcome of this collision.
Two-piece balls, which have been on the market for many years, will spin less and go a little farther off the driver than the soft, wound balata balls that were used on tour until five years ago. The hard-core two-piece ball will spin about the same as the wound ball off the wedge only if it has an extremely soft and relatively thick cover. But such a cover reduces the ball’s distance off the driver. The trick is to get a ball to spin less than a wound ball off the driver but the...
