They build the tennis ball around the air, really! Actually, the tennis ball is made in two halves and then heat wielded together to form the finished ball.

There is air inside it. Not nothing.


Does the temperature of the tennis ball affect the air?

The temperature of the ball does not affect the surrounding/outside air, but it does affect the air inside the ball.


Why does a heated tennis ball bounce higher?

A heated tennis ball bounces higher because the hot air inside the ball is lighter than the air around the ball therefore giving the tennis ball the ability to bounce higher.


What are the effects of temperature on the rebound of a tennis ball?

its is the air inside the tennis ball that you should be concerned with. Cold air is compressed and gives the ball less bounce, hot air is less dense and pushes on the sides of the tennis ball from the inside. Another important factor is altitude. altitude changes the amount of oxygen in the air. this doesnt change rebound it causes the ball to travel further in air.


What makes a tennis ball bounce?

The tennis ball is distorted from its round shape when it hits the ground, which means the volume inside is reduced or the air inside is being compressed. The air then pushes back to restore the tennis ball's original shape and therefore bounces off the ground.


A golf ball has more mass than a tennis ball because it?

It doesn't. A tennis ball has a mass of about 57g A golf ball has a mass of about 46g The golf ball is DENSER because it has material inside it (usually rubber) but the tennis ball is full of a gas (air).


Why is a golf ball heavier than a table tennis ball they are the same size?

A golf ball is heavier than a table tennis ball because it has a Higher density, the golf ball has no space inside of it while the table tennis ball has a large pocket of air.


Why is a golf ball heavier than a table tennis ball?

Because a golf ball is denser. When you cut a golf ball and a table tennis ball in half, the golf ball is solid all the way through. The table tennis ball has a cavity filled with mostly air inside.


Why do ping pong balls fly?

the ball is the same as a tennis ball. it is made out of air on the inside so it will float in the air for a while and then will endventualuy fall.


Does temperature affect the air inside the tennis ball?

It the ball has air in it, then an increase of temperature will increase the pressure within the ball, over the short term. Over the long term, all pressurized tennis balls lose pressure. If the ball is the pressureless type, it has no air to be affected by temperature.


What gas is in a tennis ball?

Generally air is the gas in a tennis ball


Why does a tennis ball not fall faster than a golf ball in free fall?

The mass of the objects don't matter in free fall - they both fall at the same time, assuming air resistance is negligible. However in your case, the golf ball has less air resistance than a tennis ball (add that to the fact tennis ball consist most of air inside adding more to the air resistance). Therefore, the golf ball falls faster than a tennis ball - Hope that helped!


Why does a heated tennis ball bounce really high?

Tennis balls have pressured air inside of them from the manufacturer. This air on days with higher temperatures will increase and expand this internalized pressure of the ball, thus making the ball more solid and hard. This increases the "bounce" of the ball


Why placing a dented table tennis ball in boiling water is one way to remove the dent in the ball?

The heat will cause the air inside the table-tennis ball (ping pong ball) to expand and so push the dint out.


Why does a hot tennis ball bounce higher than a cold tennis ball?

As the air temperature in the tennis ball raises, so does the pressure inside. As the pressure increases, the ball becomes harder and acts like one of those solid rubber super bouncy balls.


Does a room temperature tennis ball bounce higher then a heated tennis ball?

No, a room temperature ball does not bounce higher than a heated tennis ball. In fact, the heated tennis ball will bounce higher than its room temperature counterpart. This is because tennis balls rely on a high pressure internal pocket of air for their bounce. Heating the tennis ball would increase the pressure of the air inside the ball (pressure varies as temperature) which would cause the tennis ball to bounce higher. This holds (albeit for different reasons) for most solid balls as well, such as baseballs.


Why does the inside of a ping pong ball stink?

Table tennis balls are made of a type of plastic called celluloid. The odor in the ball is a by-product once the ball becomes cracked and the inside is exposed to air.

Which ball bounces the highest tennis ball or sponge ball or plastic golf ball or handball?

I believe the tennis ball would bounce the highest if you were to put equal force on each ball and throw it to the ground.I don't know exactly why, but I tested this once, and it seems the tennis ball bounces the highest because of the fact that it has the most air pressure inside of it.


How does the temperature of a tennis ball afect the height of its bounce?

Tennis balls have pressured air inside of them from the manufacturer. This air on days with higher temperatures will increase and expand this internalized pressure of the ball, thus making the ball more solid and hard. This increases the "bounce" of the ball. Vice versa for cold temperatures, the pressure will instead contract and have less pressure inside making it softer.


Is there a core in a tennis ball?

Tennis balls are made of a layer of rubber surrounding a hollow center. Then they put a thin layer of adhesive on the rubber and cover it with a layer of felt (traditionally yellow). The air pressure inside the ball is 12 psi (pounds per square inch) greater than ambient air pressure at sea level (the ’normal’ air pressure all around you). The ambient air pressure is 14.7 psi, so all together, the pressure inside the ball is 26.7 psi. The core of a tennis ball is pressurized air.


Why would a heated up ball bounce higher than a normal or froze tennis ball?

The air inside the ball expands on heating and this, in turn, makes the ball harder / more elastic.
