A ball bounces on the ground. How do the ball and the ground act on each other?(1 point)
Responses
The ball and the ground exert equal and opposite forces on each other according to Newton's third law of motion. When the ball hits the ground, the ground exerts an upward force on the ball, causing it to bounce back. At the same time, the ball exerts a downward force on the ground.
According to Newton’s third law of motion, which statement is always correct?(1 point)
Responses
The correct statement that always applies to Newton's third law of motion is: "For every action, there is an equal and opposite reaction."
Two metal balls with the same mass hang so that they are touching each other. The ball on the left is pulled to the side and released. What will happen when it swings back and hits the ball on the right?(1 point)
Responses
When the ball on the left is pulled to the side and released, it will swing back towards the right. According to Newton's third law of motion, when the ball on the left hits the ball on the right, there will be equal and opposite forces exerted between them. As a result, the ball on the right will also start moving in the opposite direction, swinging in response to the impact.
The ball and the ground act on each other through a force called the normal force. When the ball is in contact with the ground, the ground exerts an upward force on the ball known as the normal force. This force opposes the weight of the ball and prevents it from sinking into the ground. At the same time, the ball exerts a downward force on the ground due to its weight. This interaction between the ball and the ground causes the ball to bounce back up after it hits the ground.
When a ball bounces on the ground, both the ball and the ground exert forces on each other. This interaction can be explained by Newton's third law of motion, which states that for every action, there is an equal and opposite reaction.
As the ball hits the ground, it applies a downward force on the ground due to its weight. This force causes the ground to deform, compressing the surface as it absorbs the energy of the impact. Simultaneously, the ground exerts an equal and opposite force upward on the ball, known as the normal force.
The normal force acts perpendicular to the surface of the ground and prevents the ball from sinking into the ground. It is this force that propels the ball back into the air, causing it to rebound after the collision. Additionally, the ground also imparts some resistance or frictional force on the ball as it rolls or slides on the surface.
It is important to note that during the collision between the ball and the ground, energy is transferred between the two objects. Initially, the ball possesses kinetic energy, which is converted into potential energy as it reaches its maximum height during the bounce. As it descends back towards the ground, the potential energy is once again converted into kinetic energy.
