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 the desired distance and spin 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. Different types of golf balls are designed for various skill levels and playing styles, including distance balls for beginners and spin balls for advanced players seeking more control.
