A tennis ball is a small, round ball used in the sport of tennis. It is typically bright yellow or green, making it easy to see on the court. The ball is covered in a fuzzy material that helps it bounce and grip the racket. Tennis balls are designed to be lightweight, allowing players to hit them with speed and precision. When playing tennis, players use a racket to hit the ball over a net and into their opponent's court. The game can be played in singles or doubles format. A good tennis ball can make a big difference in the quality of the game, as it affects how the ball bounces and travels.
