Did you know that the temperature of a tennis ball affects its performance?
Inside each tennis ball is a hollow core – a rubber, coated space containing gas. As the temperature of the ball changes, the pressure of the gas inside it changes and it changes the physical dynamics of the ball. The temperature of tennis balls affects how the ball bounces. The higher the temperature the ball acts very differently on a cold court
As the temperature of the tennis ball decreases, the gas molecules contract and the ball bounces downwards.
The 54,250 tennis balls used during Wimbledon are kept at exactly 68 F as the heat affects the performance of the ball. After the first seven – nine games the balls change completely. Each one is checked for bounce and weight – for this, a ball must bounce 135 to 147 cm after being thrown from a height of 100 inches to a concrete floor.
