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.

How does air pressure affect a basketball?

Ball Pressure



Basketballs are inflated with air to make them bounce. 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.

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. Do this several times, until the ball is completely inflated.

How high should an NBA ball bounce when dropped?

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”

Can you pop a basketball?

Basketballs don’t really pop, actually. Not usually. One of my shots once took a funny bounce off my driveway hoop, a car ran over the ball and it popped extraordinarily loudly. Like a gunshot, almost.

Is it bad to deflate a basketball?

Deflating it completely can sometimes cause the leather or synthetic panels to separate and ruin the ball. It is not something that will definitely happen but something to look out for. Just make sure you deflate it slowly and keep an eye on the ball. There is no need to worry about this for all rubber balls.

Why does my basketball 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. To get the most out of your basketball it is very important to keep it at its recommended air pressure, and to inflate and deflate it correctly.

How do you fill a basketball without a air pump?

A punch balloon would work very well. Blow up the balloon as much as possible. Then, using a paper clip or clamp, close off the balloon’s lip to keep the air inside. Next, attach the pump needle or straw/stirrer to the balloon and insert the other end into the ball’s hole.

Does the air pressure in a basketball affect your shot?

The air pressure in a basketball can’t affect how you play and how good your shot is. Ones shot can defer at anytime and it really doesn’t depend on the air pressure in the ball.

What happens to the air pressure inside the ball when it is kicked?

The air pressure increases inside the ball when it is kicked. This is because pressure in terms of volume can be derived as: By using the formula if you both of these outcomes will increase the air pressure of the ball when it is kicked.

Why does the pressure in a basketball increase when more air is pumped in?

Why does pumping more air into a basketball increase the pressure inside the ball? 2. The more gas particles inside the basketball the more collisions (crashes of the particles against one another). The more collisions inside cause more push out (pressure) of the gas.

How does temperature affect air pressure in a basketball?

This is because the gas molecules inside the ball expand as temperature increases. As the gas molecules expand, their energy increases and they bounce around faster inside the ball. That’s why higher pressure leads to a higher bounce of the ball. Likewise, a lower temperature will lead to a lower pressure.
