When a ball bounces off the ground, there are action and reaction forces involved.
The action force is the force applied by the ball onto the ground when it comes in contact with it. This force pushes the ground downwards.
The reaction force is the force exerted by the ground onto the ball. It is equal in magnitude but opposite in direction to the action force. This reaction force propels the ball upwards.
Inside the ground, there are balanced forces. These forces are equal in magnitude and in the same direction. They help to keep the ball in place.
As the ball bounces out of the ground, the balanced forces change. The reaction force from the ground becomes stronger than the action force applied by the ball. This is because the ground exerts a greater force to propel the ball upwards. These forces are still in the same direction.
However, as the ball leaves the surface of the ground and starts its upward trajectory, the direction of the balanced forces changes. They are now opposite in direction, but the magnitude of the forces remains the same.
Overall, during the bouncing motion, the action and reaction forces between the ball and the ground change in magnitude and direction.
When I bought bounces what action and reaction forces to the ball in the ground exert, the balance forces the same as out of the ground, and they go in the same direction, the balance forces stronger than that of the ground, and they go in the same direction a bow in the ground, exert force of the same magnitude, but an opposing directions to balance forces stronger than out of the ground and then going opposite directions
