The main aim in the game of golf is to take as few strokes as possible to hit a ball certain distance into a cup set in the ground. Golf as we know it today originated from a game played on the eastern coast of Scotland in the Kingdom of Fife during the 15th century. Golf clubs are used to hit a golf ball. Each club is composed of a shaft with a grip on the top end and a club head on the bottom. Woods are mainly used for long-distance fairway or tee shots; irons, the most versatile class, are used for a variety of shots; putters are used mainly on the green to roll the ball into the cup. The golf players are allowed up to 14 clubs, which they carry in a bag or trolley. Most players have three or four woods, nine or ten irons, and one putter. The ball is supported for the first stroke of each hole on a small stand or tee. The player must wear studded shoes. The ruling authorities of golf, the Royal and Ancient Golf Club of St Andrews (R&A) and the United States Golf Association (USGA), reserve the right to define what shapes and physical characteristics of clubs are permissible in tournament play.
