Ball Pressure
The internal air pressure of an inflatable or pressurised ball, which governs how firm it feels and how high it bounces.
Definition
Ball pressure is the amount of air pressure held inside a ball relative to the surrounding air. In inflatable balls such as those used in football, basketball and volleyball it is set by inflating to a recommended range, while pressurised tennis balls are sealed with internal pressure that makes them lively and quick off the strings.
Higher pressure makes a ball firmer, faster and higher-bouncing, whereas low pressure makes it feel soft and sluggish. Pressurised balls slowly lose air and go 'dead', which is why tennis balls are sold in sealed cans and replaced regularly; pressureless balls avoid this by relying on the rubber itself rather than trapped air.
Scope: Each sport's governing body sets its own permitted pressure range; the values vary, so official rules should be consulted for exact requirements.

Techniques
- VolleyA shot played near the net by blocking the ball out of the air before it bounces, using a short, firm punch rather than a full swing.
- Kicking in rugby unionThe kicks rugby union is played with — punt, grubber, box kick, up-and-under, drop kick and place kick — what each achieves and which law governs its use.
- Flat, slice and kick servesThe three serves and what actually separates them — the contact point on the ball and the toss that makes it possible — plus what each one does to the ball after it bounces.
- Topspin ForehandA forehand groundstroke hit with a low-to-high swing that puts forward spin on the ball so it dips and kicks up on landing.
Equipment
- The padel ballThe padel ball's own specification — diameter, weight, bounce and internal pressure — and the separate altitude ball the rules provide for above 1,000 metres.
- The rugby union ballThe oval ball that shapes how rugby union is passed and kicked — its weight, air pressure, construction and the provision that lets younger players use a smaller one.
- The table tennis net assemblyThe net, its posts and its suspension — the one height that governs both the net and the posts, and why that number appears twice in the Laws.
- Football (soccer ball)A round, inflated ball used to play association football and futsal. Futsal uses a smaller, heavier ball that bounces far less on a hard court.
- Golf ballA small, firm, dimpled ball struck with a club and played toward the hole on a golf course.
