Tennis is one of the most popular sports in the world. It has a long history and many different types of tennis. The game is played with a racquet and a ball, both of which are made of leather. A tennis racket is made from wood or metal and it has a head of netting to help keep the ball in play.
The ball is usually white but can be colored. The ball is about the size of a basketball.
The game was first played in England during the sixteenth century. The game was very popular at that time because it was believed that playing tennis would improve a person’s health.
In 1877, the first official rules were written down and these rules have been used ever since. In the beginning the rules were not very strict and players were allowed to hit the ball with any part of their body except the hand.

Today the rules are more strict. Players are allowed to use only the hand to hit the ball. They must hit the ball over the net and they may not hit the ball out of bounds. Players may not hit the ball with any part other than the racket.
There are four different ways to serve the ball. The player may serve the ball by bouncing it, tossing it, hitting it with the racquet, or hitting it with the hand.
The player serves first and then the other player returns the ball. Players alternate serving until one player wins.
The ball is returned by the player who hits the ball first. The player hits the ball over the net with the racquet. If the ball touches the net before it goes over the net, it is called a fault.
A player wins when he gets seven points. He gets three points if he serves the ball into the opponent’s court. He gets two points if he hits the ball over the net into his opponent’s court. He gets one point if he hits the ball out of bounds.
If the ball hits the net before going into the opponent’s court, it is called a double fault. If the ball hits the net twice before going into the opponent’s side, it is called a triple fault. If the ball hits a net once, it is called a fault.
