When the ball is heated, it becomes more elastic, as the bonds are able to move more freely and thus are able to stretch more than those in a cooler ball, and thus less energy is lost (Portz, 2011). This then means that the ball bounces higher.
Why do squash balls need to be warmed up?
Why does a squash ball have to be warmed up? Squash balls need to be hit warm before you can start the game. If you just start the game straight away, the ball won´t bounce enough to have a good game.
How do I make my squash ball more bouncy?
The best way to warm up a squash ball is by repeatedly hitting it straight down the line high up on the front wall. Volleying works really well for this, as then the ball also doesn’t cool down when it hits the floor. Volley three times and then cross court it to your partner.
Do hot balls bounce higher?
As the temperature decreases, gas molecules move closer together. This causes them to move around more slowly with less energy. Thus, lower pressure leads to a lower bounce of the ball.
What causes a ball to bounce higher?
When the ball hits the ground, all that kinetic energy has to go somewhere. A lot of it goes back into the ball, giving it more force to pop back up into the air—so the higher the potential energy, the higher the kinetic energy, and the higher the kinetic energy, the higher the bounce!
What balls do professional squash players use?
The Dunlop Pro double yellow dot squash ball is the most used squash ball in the world. This is the official ball of the World Squash Federation, Professional Squash association and Women International Squash Players Association. It is the only ball used in international professional play.
Which squash ball bounces more?
The ball with a white dot or ‘Start Squash Ball’, is designed for beginners. The Start has up to 40% more bounce than the ‘Prime Squash Ball’. This makes it easier to keep a rally going and also gives the highest bounce. It doesn´t need to be warmed up before you can start the game.
What do dots mean on squash balls?
Squash Balls: What Do the Coloured Dots Mean?
| Dot colour | Bounce height | Suggested player level |
|---|---|---|
| Double yellow | Low | Experienced player |
| Yellow | Low | Good player |
| Green | Low/Medium | Good player |
| Red | Medium | Beginners |
What is the fastest squash ball?
The fastest speed of a squash ball (male) is 267.151 km/h (166 mph), and was achieved by David Hilton III (USA) in Philadelphia, Pennsylvania, USA, on 11 June 2021. The attempt took place at the Arlen Specter US Squash Center to celebrate the 20th anniversary of the SquashSmarts organization.
What is the difference between single dot and double dot squash balls?
The Different Types of Squash Ball:
For beginners or children there is a single white dot ball. The difference between these balls is in their bounce. Your level determines which ball is the most suitable for you. The squash ball with a double yellow dot is called the HEAD ‘Prime Squash Ball’.
How does temperature affect bounce balls?
One factor that can influence the bounce of a ball is the temperature of the ball. A warmer ball will bounce higher than a cold one. The reason for this is twofold. In a hollow ball, the change in temperature causes a change in air pressure within the ball.
What environmental factors affect the bounce of a ball?
The combination of the material properties of a ball (surface textures, actual materials, amount of air, hardness/ softness, and so on) affects the height of its bounce.
How does temperature affect rubber?
This occurs because of the unusual polymer structure of rubber. When the long chains get hotter and vibrate, they actually shorten, causing the material to contract. When the chains cool down, they relax and stretch out, causing the material to expand.
What surface makes a ball bounce higher?
The harder the court surface is the more energy a dropped ball retains and the higher it rebounds. A basketball bounces pretty well on hardwood, but even better on concrete. But, if the floor is too hard, it can lead to serious player injuries.
What energy causes a ball to bounce?
Elastic potential energy
Elastic potential energy is what causes a ball to bounce, or rebound, because it is transformed into kinetic energy, which is then used to bring the ball back up.
How does the material of a ball affect its bounce height?
A hard surface, like concrete or hardwood, hardly absorbs any, so most of the kinetic energy of the fall goes into bouncing the ball back up. A soft surface, like grass or carpet, absorbs more energy from the fall, so there’s less left to push the ball back up, and it bounces pretty badly.
How much should a squash ball bounce?
| Colour | Bounce | Suggested player level |
|---|---|---|
| Double yellow | Slow | Experienced squash players |
| Yellow | Slow | Advanced |
| Green | Medium/slow | Advanced |
| Red | Medium | Beginners |
What is a squash ball called?
The “double-yellow dot” ball, introduced in 2000, is the competition standard, replacing the earlier “yellow-dot” ball. There is also an “orange dot” ball for use at high altitudes.
Is there a uniform rule for female squash players what is it?
Playing clothing shall consist of:

What are squash balls made of?
The material that makes up a squash ball is raw butyl rubber, many different natural and synthetic materials and powders (that are added to the rubber in the process explained below) and air that is enclosed inside the rubber ball. Various types of balls are produced for various speeds and playing styles.
How hot do squash balls get?
Squash balls used by professional players are hot to the touch and feel like mini hot-coals if you were to hold one after a particularly hard-hitting rally.
