Why do balls bounce so high?
When a rubber ball hits something, it absorbs energy and releases energy really fast, Zheng said. When it hits something, it stops, and the kinetic energy is stored inside the ball as internal energy. Then it can quickly convert the internal energy back into kinetic energy which allows the ball to bounce back.
Do basketballs lose their bounce?
Yes, the age of a basketball will affect how well the ball bounces. An old basketball may have very slowly leaked some of its air out and become flatter than a new one. … The same is true for basketballs made of natural rubber — they can become cracked and brittle after many years in the garage.
Why balls dont bounce forever?
The law of conservation of energy implies that a bouncing ball will bounce forever. Of course, it does not. When you drop it on the floor, it changes some of its energy into other forms, such as heat, each time it hits the floor.
Do heavier balls bounce higher?
A well-inflated ball bounces better because it has more air inside. … When the lighter ball bounces on the heavy ball they exchange energy, and the lighter ball flies off with some of the energy of a heavier ball. It reaches way higher than from the height it was released.
Where does a basketball bounce best?
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.
Why does a ball bounce less on carpet?
A hard surface, such as concrete, absorbs less energy compared with a soft surface, such as a carpeted floor. The more energy absorbed by the surface, the less that remains in the ball for it to bounce.
How much energy does a ball lose when it bounces?
For example, if a ball bounces 80% of its height on each bounce, then the ball is losing 20% of its energy on each bounce. The time of each bounce is about 90% of the time of the previous bounce, the ball slows down about 10% each bounce, and about 10% of the linear momentum is lost at each bounce.
Why do basketballs deflate in cold weather?
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 a fully-inflated ball might appear deflated if the temperature drops dramatically.
Is water bad for a basketball?
Rain or shine, hot or cold, neither indoor or outdoor basketballs should be left outside in extreme conditions. Any type of wetness can ruin the quality of your ball and make it lose its grip. Severe temperatures can also warp the shape of your ball and affect performance.
Can heat inflate a ball?
The NBA states that a basketball must be inflated between 7.5 and 8.5 lb. of pressure. Using the ideal gas law and assuming that a ball is filled at room temperature, we can estimate that for every 10 degrees of temperature change, a ball will increase its pressure by one pound.
