How much does a basketball bounce?

NBA rules dictate that basketballs should be inflated to between 7.5 and 8.5 pounds per square inch. If the basketball is inflated below this level, it won’t bounce correctly. If it is inflated above this level, the basketball could be damaged or burst.

How high does the average basketball bounce?

If you drop a basketball without throwing it at the ground, it will bounce back up to a fraction of its original height that is not too far from 1.0 (0.75 is kind of typical for a well-inflated new basketball). So if you drop a basketball from height of 20 feet, you might expect it to go back up 15 feet or so.

How long does a basketball bounce?

According to Spalding, the average lifespan of an NBA basketball is about 10,000 bounces.

How many PSI is a basketball?

An NBA regulation ball is inflated to between 7.5 and 8.5 psi. By regulating a basketball’s air pressure, the NBA can ensure fair playing conditions.

Can you pop a basketball?

A basketball is 9.23” in diameter, which means the surface area is 4*pi*(9.23/2)^2 = 267.64 square inches. A ball is inflated to about 8 PSI, so it would take 2141 pounds of force to crush a ball.

Can a basketball be too bouncy?

Hold the ball up to your face and slowly let it drop. If the bottom of the ball bounces up past your waist or slightly higher, then it is fully pumped. If the basketball bounces up close to the chest, it means it has too much air. If it does not bounce up to the waist, it means there is not enough air.

Why does a ball stop bouncing?

If you drop the basketball, the force of gravity pulls it down, and as the ball falls, its potential energy is converted to kinetic energy. … This is because the basketball had an inelastic collision with the ground. After a few bounces, it stops bouncing completely.

Why do balls bounce differently?

This is because the higher the starting height of the ball, the higher the ball’s potential energy. … 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!

Where does the energy go when a ball bounces?

As the ball falls, that energy is converted to kinetic energy. When the ball collides with the floor, some of this kinetic energy is transferred to the floor and converted to thermal energy (friction) and elastic potential energy (ball deformation.)

How hard should you pump a basketball?

NBA rules dictate that basketballs should be inflated to between 7.5 and 8.5 pounds per square inch. If the basketball is inflated below this level, it won’t bounce correctly. If it is inflated above this level, the basketball could be damaged or burst.

Why do basketballs lose air?

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.

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.
