Game Tennis is a popular sport that involves two players or two teams of two players each. The objective of the game is to hit a ball over a net using rackets and score points by making the ball land in the opponent's court. The term 'SERVE' is used to describe the action of hitting the ball from one side of the court to the other. It is the first shot of the game and is usually done with an underhand motion. The player who serves must make sure that the ball lands within the boundaries of the court and that it does not touch the net.
