How much does a golfball weight?
how much does a golfball weight, and how many times can a golfball bounce before it stops bouncing, and what's the diameter of a golfball, and how many indents does a golfball have?
A ball must not weigh more than 1.620 ounces avoirdupois (45.93gm).
How many times can a golf ball bound before it stops? Well, that's just a crazy question! There's certainly no rule on this.
The ball must have a diameter of not less than 1.680 inches (42.67mm).
Golf balls don't have indents, but they do have dimples. The number varies, depending on the manufacturer and model. The only rule that the USGA has is that the dimples must be uniform over the entire surface of the ball (some "illegal" balls have deeper dimples around the perimeter and shallower ones around the "poles", thus dramatically reducing slices).
Unlike any other ball, the golf ball has evolved considerably, from the earliest wooden balls of the fifteenth century to the featheries of the seventeenth century to the gutta-percha balls of the nineteenth century and finally to the high-tech balls of the 1990s.
The earliest golf balls, dating back to Roman times, were made of smoothly carved boxwood. Wood balls were in fashion until the 1600s when they were replaced by golf balls called "featheries". Featheries were made of boiled goose feathers stuffed tightly within a stitched cowhide casing. The ball became very hard as the feathers dried. Gutta-percha balls began replacing featheries around 1848. These balls were made from dried gum of the Malaysian sapodilla tree. In 1898, a three-piece rubber-core ball was invented. It consisted of lengths of rubber yarn stretched around a rubber core. The three-piece, balata-covered ball was the newest and most costly invention. It consists of a liquid center, a polyurethane interlayer, and a synthetic balata cover.
Golf balls have dimples because when it is hit, it spins as fast as eight thousand revolutions per minute. As the ball spins, the dimpled surface traps a layer of air that rotates with the ball, like a small whirlwind around the ball's surface. Without dimples, the ball would travel only about three-fourths as far.
The United States Golf Association (USGA) set restrictions on the weight and size of the golf ball. The weight of the ball should not exceed 1.620 ounces (0.04593 kg) and must have a diameter of at least 1.680 inches. The association also regulated the coefficient of restitution (COR) of the ball, about 0.6. This means that if a golf ball strikes a solid surface at a speed of 10 m/s it must rebound at a speed of 6 m/s.
Hope this helps. Good luck. Happy Holidays.
