A lot of people like playing tennis. Some of you might be wondering how a tennis ball can bounce. It has to do with the material of the ball. Modern tennis balls are made of hollow rubber, and covered with wool or nylon shell which is known as the nap. The air inside the ball makes it bounce. The air inside the ball has high pressure, if the pressure in the ball is not high enough it will make a thud when it hit the ground. The temperature inside the ball also makes a difference of the bounce of the ball. Dropping anything has a lot of different forces going on the object. Like a book, if you drop it on the side with the greatest surface area, there will be gravity pulling the book down and air pushing the book up. The mass, density, and volume are also a part of the way the ball bounces. The mass of a tennis ball is between 2 and 2 1/16 which is 57.7 and 58.5 grams. Who knows because different companies that make tennis balls make their balls in different ways. The volume of a tennis ball is about 8 cubic inches. This makes the density fall between 0.44013375242 and 0.4462361268 grams. …show more content…

The reason that tennis balls bounce in the first place is because the air on the inside of the ball pushes outwards. When the ball hits the ground, the side of the ball squishes inwards and the air on the inside of the ball pushes out again, and that's what pushes the ball back up off the ground.”(Tamara, published on 10/22/2007, copyright date unknown) Did you know that tennis balls also lose their bounce after removed from their vacuum can. The reason for this is because the vacuum can has the same pressure as the inside of a tennis ball. “Once you take the balls out of the can, there's more air pushing on the inside than on the outside, and a little bit of that air actually manages to push its way through the outside of the ball.
