Golf
balls
The minimum allowed diameter of a golf ball is 42.67mm and its mass
may not exceed 45.93g. Modern golf balls have a two-, three-, or
four-layer design constructed from various synthetic materials.
The surface usually has a pattern of 300-400 dimples designed to
improve the ball's aerodynamics. The method of construction and
materials used greatly affect the ball's playing characteristics
such as distance, trajectory, spin and feel.
Harder materials, such as Surlyn, usually result in the ball's traveling
longer distances, while softer covers, such as Balata, tend to generate
higher spin, more "feel" and greater stopping potential.
Golf balls are separated into three groups depending on their construction:
two-, three-, or four-piece covers. Generally four-piece golf balls
tend to be the most expensive, though price is no assurance of quality.
As of 2006 there are golf balls that utilize RFID technology, which
allow golfers to locate errant shots easily using a handheld homing
device. The first type of golf ball was the feathery, made out of
leather anf feathers. |
