Tennis is a popular sport played between two players (singles) or two teams of two players each (doubles). The objective is to hit a tennis ball over a net and into the opponent's court, aiming to score points by making it difficult for the opponent to return the ball. Players use a tennis racket to strike the ball, and matches can be played on various surfaces, including grass, clay, and hard courts. The game has a rich history and is governed by the International Tennis Federation. Major tournaments, such as Wimbledon and the US Open, attract millions of fans worldwide. Tennis not only promotes physical fitness but also encourages strategic thinking and sportsmanship.
