Golf balls are small, round objects used in the sport of golf. They are typically made of a rubber core surrounded by a layer of plastic, which helps them achieve distance and control when struck by a golf club. Standard golf balls have a diameter of about 1.68 inches and weigh approximately 1.62 ounces. The surface of a golf ball is covered with dimples, which improve its aerodynamics and help it fly farther and more accurately. Different types of golf balls are designed for various skill levels and playing styles, catering to both beginners and professional players.
