Tennis

Tennis is a racquet sport that opposes either two players (this is called a singles game) or four players who form two teams of two (a double). Players use a racket strung vertically and horizontally (in a sieve) at a tension varying with power or spin. This racket, which can vary in materials, is used to hit a rubber ball, filled with air and covered with felt. The object of the game is to hit the ball with no more than one bounce so that the opponent cannot put it back in bounds, either by scoring the point by putting the opponent out of reach of the ball or by forcing him to commit a foul.
