Ball bounces on the ground how do the ball in the ground act on each other?
When a ball bounces on the ground, the ball and the ground exert forces on each other.
As the ball hits the ground, it exerts a force on the ground, pushing it downward. This force is the result of the ball's weight and its initial momentum.
Simultaneously, the ground exerts an equal and opposite force on the ball, pushing it upward. This force is known as the normal force, which is perpendicular to the surface of the ground. It prevents the ball from sinking into the ground and enables the rebound motion.
The ball's elasticity also plays a role. If the ball is highly elastic, it compresses upon impact with the ground, storing energy temporarily as potential energy. As the ball decompresses, this potential energy is converted back into kinetic energy, causing the ball to bounce back up.
However, if the ball is not very elastic, or the ground is not very rigid, some of the energy may be dissipated as heat or deformation, resulting in a less pronounced bounce.
