Tennis players use a racquet to hit a small ball over a net. They must make it land it in the court. They get points if the other person can't hit the ball back.
The players can hit the ball on the full or let it bounce once. Then they have to hit it back.
To start each game a player serves.
This is when they hit the ball into the serving area on the other court. To serve the players throw the ball up above their head and hit it.
The players need to be fast on their feet. They also need to be good at hitting.
Olympic competition includes men's and women's singles and men's and women's doubles.
In Sydney, the players will be on a hardcourt, which offers medium ball speed.
