When a basketball hits the ground an elastic collision takes place. … The collision between a basketball and the ground is about 80% elastic so 80% of the kinetic energy is conserved. The other 20% is consumed by thermal energy, which comes from internal frictional forces in the ball and the ground.
Why do balls eventually 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 are perfectly elastic collisions rare?
Perfect elastic collisions are rare because usually some heat is generated during a collision. However, as seen with the colliding billiard balls, the collision doesn’t cause any permanent damage to the objects involved.
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” …
What are the 3 types of collision?
Collisions are of three types:
- perfectly elastic collision.
- inelastic collision.
- perfectly inelastic collision.
