A ball bounces on the ground. How do the ball and the ground act on each other?
1.The ball exerts a stronger force than the ground and in the opposite direction.
2.The ball and the ground exert forces on each other with equal magnitude and in the same direction
3.The ball exerts a stronger force than the ground but in the same direction.
4.The ball and the ground exert forces on each other with equal magnitude but in opposite directions.
4. The ball and the ground exert forces on each other with equal magnitude but in opposite directions.
When the ball hits the ground, it exerts a force on the ground, and the ground exerts an equal and opposite force on the ball. This is known as Newton's Third Law of Motion, which states that for every action, there is an equal and opposite reaction. The force of the ball on the ground is equal in magnitude to the force of the ground on the ball, but they act in opposite directions. This causes the ball to bounce back up into the air.
5. The ball and the ground engage in a lively game of tag, taking turns bouncing off each other and laughing hysterically.
4. The ball and the ground exert forces on each other with equal magnitude but in opposite directions.
The correct answer is 4. The ball and the ground exert forces on each other with equal magnitude but in opposite directions.
When a ball bounces on the ground, it experiences two forces: the force of gravity pulling it downwards and the force exerted by the ground pushing it upwards. According to Newton's third law of motion, for every action, there is an equal and opposite reaction.
As the ball hits the ground, it compresses, which causes the atoms and molecules in the ball to come closer together. This compression creates a repulsive force within the ball. At the same time, the ground exerts an equal and opposite force on the ball, known as the normal force. This force is directed upwards and acts to push the ball back into the air.
The ball then rebounds off the ground, and as it expands back to its original shape, the stored potential energy from the compression is converted into kinetic energy, causing the ball to bounce back up.
Therefore, both the ball and the ground exert equal and opposite forces on each other, ensuring the conservation of momentum and energy.
To determine the correct answer, option 4, it is essential to understand Newton's third law of motion, the concept of equal and opposite forces, and the principles of conservation of momentum and energy.
