Tennis Ball
A tennis ball is one of the basic pieces of equipment in the game of tennis. Tennis is a racket sport played between two players (singles) or two teams (doubles) and the aim is to score points by hitting the ball into the opponent's court. The main characteristics of a tennis ball:
Material: Tennis balls are usually made of high-quality rubber. This material allows the ball to bounce on hard surfaces and control the speed of the game.
Size: A standard tennis ball is approximately 2.7 inches (6.7 cm) to 2.85 inches (7.3 cm) in diameter.
Weight: A standard tennis ball weighs approximately 2 ounces (57 grams) to 2.1 ounces (59.4 grams).
Pressure: Tennis balls are held at a certain air pressure. They usually have an air pressure in the range of 12-16 psi (pounds per square inch).
Color: Traditionally tennis balls are yellow, but they are also produced in white or other colors.
Surface Pattern: The pattern on the surface of tennis balls allows the ball to glide across the ground and control its direction. This pattern helps the ball to spin (rotate) and helps players to control the ball better.
Tennis balls are an important factor affecting the speed and performance of the game. Balls of different hardness and air pressure can change the characteristics of the game. Especially professional tennis players choose the hardness and surface of the balls according to their preferences.
Tennis balls are used on a variety of surfaces, indoor and outdoor courts, and must meet certain international standards. They are an important piece of equipment that allows players to control their game and hit with their racquets as they wish.
