What makes tennis balls bounce?

This bounce is caused by air that's pumped into the ball. As the air pushes against the inside of the ball it creates pressure. When the ball hits the ground the air trapped inside the ball is forced inwards. When the air on the inside pushes back the ball is propelled back off the ground, thus creating the bounce.

The main reason is the way air leaks out of the balls over time. Although the rubber core is chosen to have a low 'permeability' to gas molecules (i.e. it doesn't let too many through), it cannot keep them all inside. Eventually, enough will leak out that the pressure reduces significantly and the balls feel softer.

Are tennis balls filled with air?

There is a thin layer of adhesive on the rubber. Pressurized tennis balls are filled with either air or nitrogen, with nitrogen keeping the balls inflated longer. On the other hand, non-pressurized balls are solid, which keeps them from deflating.

Does a tennis ball have air?

Pressurized tennis balls are hollow and contain air at a pressure of about 26.7 psi (though some balls may be pressurized much lower). Pressurized tennis balls are designed this way to reduce weight and increase bounce.

Why were tennis balls changed to yellow in 1986?

The Yellow Ball

Did you know that a tennis ball takes 400 years to decompose? Nationwide, approximately 125 million used tennis balls wind up in America's landfills every year. That is 20,000 metric tons of methane-producing, near non-decomposable rubber waste.

How many tennis balls are wasted?
