How much PSI is in a basketball?

An NBA regulation ball is inflated to between 7.5 and 8.5 psi.

How do you measure air pressure on a basketball?

A quick way to check if your ball has the proper air pressure is by taking this simple test. Drop your basketball from the height of your shoulder and leave it to bounce. If it bounces up back to the height of your hips, then your ball probably has the appropriate air pressure required to deliver on the court.

How do you tell if a basketball is properly inflated?

If you don’t have a pump with a air pressure gauge, you can reasonably judge whether the basketball is properly inflated by this method: Hold the ball in front of your face and drop it if it bounces up to your belt buckle, then it is properly inflated.

Will more air inside a basketball make it bounce higher?

With more air in the ball, the air starts at higher pressure and pushes back that much harder when the ball is bounced. So that short answer is that more inflated basketballs bounce better because they have more air pressure inside them. Then use the pump to put a bit of air into the ball.

What happens if you over inflate a basketball?

An overinflated ball can be bad as well. It will bounce too high when you dribble, bank too hard off the backboard and bounce passes will go farther than you intend them to go.

Basketballs tend to lose a little air when left unused and through normal use over time. In order to bounce properly, basketballs need the right amount of air pressure. When a ball is manufactured and inflated, it is drop-tested to determine its ideal air pressure which is then printed on the ball near the hole.

How high should the basketball bounce?

Rule 1-12-2 says: “The ball shall be inflated to an air pressure such that when it is dropped to the playing surface from a height of 6 feet, measured to the bottom of the ball, it shall rebound to a height, measured to the top of the ball, of not less that 49” when it strikes on its least resilient spot, nor more than

How does air pressure affect bounce height?

In general, the higher the air pressure is inside the basketball, the higher it will bounce. If a ball is not inflated fully, it will bounce low and erratically. On the other hand, excessively over-inflating a ball might break the bladder and cause leaks, negatively impacting the consistency of the ball’s bounce.

How do you stop a basketball from leaking air?

Ball Leak — Option 1 Submerge the basketball in a tub of water and rotate it, watching for exiting air bubbles to indicate the source of your leak. Dry the area off and mark the leak with pencil or tape.

Why does my basketball feel heavy?

That means that the air in a properly inflated basketball pushes outward with a force of 7.5 to 8.5 pounds on each square inch of the inner surface of that ball. That outward push stretches the ball tight and gives it its feel and bounciness.

How high does a basketball bounce when dropped from 5 feet?

According to international basketball rules, a basketball is properly inflated “such that when it is dropped onto the playing surface from a height of about 1.80 m measured from the bottom of the ball, it will rebound to a height, measured to the top of the ball, of not less than about 1.2 m nor more than about 1.4 m”

Why do balls flatten?

When you drop a ball, gravity pulls it toward the floor. The ball gains energy of motion, known as kinetic energy. When the ball hits the floor and stops, that energy has to go somewhere. The energy goes into deforming the ball–from its original round shape to a squashed shape.
