Tennis
Definition and Overview
Tennis is a racquet sport played between two players (singles) or four players (doubles) on a rectangular court with a net in the center. The objective is to hit the ball over the net into the opponent's court while preventing the opponent from doing the same. Tennis is a physically demanding sport that requires speed, agility, and hand-eye coordination.
History of Tennis
Tennis has a rich and storied history that dates back to the 12th century in France. The modern game of tennis emerged in England in the 16th century, where it was played by the upper class. The first Wimbledon Championship was held in 1877, and it remains one of the most prestigious tennis tournaments in the world. The International Tennis Federation (ITF) was established in 1924 to govern the sport globally.
Equipment and Rules
Tennis is played with a racquet, a ball, and a net. The racquet is made of materials such as graphite, titanium, or aluminum, and is designed to provide power and control. The ball is made of felt-covered rubber and is pressurized to 12.5 psi. The net is 3 feet 6 inches high in the center and 3 feet 6 inches high at the sides.
A tennis match is divided into sets, with a standard match consisting of best two out of three sets. A set is won by the player who first wins at least six games, provided they win by a margin of two games. If the score is tied at 6-6, a tiebreaker is played.
