Question

$Please \: answer$
Why does a ball bounces after hitting a surface? Is there a repulsive gravitational force acting here? ​

Answer 1

When a basketball bounces off of a surface, some of its energy is absorbed by that surface. ... 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.
