New balls tennis
You're referring to the new balls used in tennis!
In professional tennis, the balls used are made of a special type of rubber called "pressurized rubber" and are designed to withstand the high-speed impacts and intense spin of the game. Here are some interesting facts about the new balls used in tennis:
- Pressure: The balls are pressurized to 12-15 PSI (pounds per square inch), which is higher than the pressure in a car tire!
- Material: The balls are made from a combination of rubber, synthetic rubber, and other materials. The exact composition is a trade secret, but it's a special blend that provides the right balance of bounce, feel, and durability.
- Size: The balls are 2.57 inches (6.5 cm) in diameter, which is slightly smaller than a golf ball.
- Weight: The balls weigh around 2 ounces (57 grams), which is roughly the same weight as a small apple.
- Bounce: The balls are designed to bounce at a consistent height of around 58 inches (147 cm) when dropped from a height of 6 feet (1.8 meters).
- Spin: The balls are designed to withstand the intense spin generated by professional tennis players, with some balls spinning at speeds of over 3,000 revolutions per minute!
- Lifespan: The balls are designed to last for around 7-10 games, depending on the level of play and the conditions. After that, they may start to lose their bounce and consistency.
The new balls used in tennis are manufactured by a few companies, including Wilson, Dunlop, and Penn. Each company has its own unique design and technology, but they all aim to provide the same level of performance and consistency for players.
