Tennis is a popular racket sport played on a rectangular court divided by a net. It can be played individually against a single opponent (singles) or between two teams of two players each (doubles). The objective of the game is to hit the ball over the net and into the opponent's court in such a way that they cannot return it. Points are scored by winning rallies and games, with the ultimate goal being to win enough games to win a set and ultimately the match. Tennis requires agility, strategy, and skill, making it a challenging and engaging sport for players of all ages and skill levels.
