When a ball bounces on the ground, the interaction between the ball and the ground involves several forces at play:
1. Normal Force: The ground exerts a normal force on the ball in an upward direction. This force is perpendicular to the surface of the ground and prevents the ball from sinking into the ground.
2. Gravitational Force: The Earth exerts a gravitational force on the ball, pulling it downwards. This force gives the ball its weight and determines how strongly it is attracted towards the ground.
3. Elastic Force: As the ball hits the ground, it gets compressed, causing the shape of the ball to change temporarily. This compression leads to an elastic force, also known as the reactive force, which acts in an upward direction to push the ball back up.
4. Frictional Force: When the ball initially hits the ground, there is a brief moment where the ball comes to a halt due to friction. This frictional force acts opposite to the velocity of the ball and helps decelerate it before the elastic force propels it back up.
Overall, these forces between the ball and the ground act on each other to determine the direction and intensity of the bounce, as well as the behavior of the ball and the ground during the interaction.
