Tennis

Tennis is a racket sport that can be played individually against a single opponent or between two teams of two players each. Each player uses a tennis racket that is strung with cord to strike a hollow rubber ball covered with felt over or around a net and into the opponent's court. The objective of the game is to play the ball in such a way that the opponent is able to play a valid return. The player who is unable to return the ball will not gain a point, while the opponent will.
