A ball bounces on the ground. How do the ball and the ground act on each other?(1 point)

Responses

The ball exerts a stronger force than the ground and in the opposite direction.
The ball exerts a stronger force than the ground and in the opposite direction.

The ball exerts a stronger force than the ground but in the same direction.
The ball exerts a stronger force than the ground but in the same direction.

The ball and the ground exert forces on each other with equal magnitude and in the same direction.
The ball and the ground exert forces on each other with equal magnitude and in the same direction.

The ball and the ground exert forces on each other with equal magnitude but in opposite directions.

9 answers

The correct response is:

The ball and the ground exert forces on each other with equal magnitude but in opposite directions.

This statement reflects Newton's Third Law of Motion, which states that for every action, there is an equal and opposite reaction. When the ball bounces on the ground, it exerts a force on the ground, and the ground simultaneously exerts an equal force on the ball in the opposite direction.

If two moving objects collide, then they will bounce off each other.
If two moving objects collide, then they will bounce off each other.

If two moving objects collide, then both will stop moving.
If two moving objects collide, then both will stop moving.

If a moving object hits another object, then the second object will push back.
If a moving object hits another object, then the second object will push back.

If a moving object hits another object, then the second object will start moving.

The correct response is:

If a moving object hits another object, then the second object will push back.

This statement is in accordance with Newton's third law of motion, which states that for every action, there is an equal and opposite reaction. When one object exerts a force on another, the second object exerts an equal force back on the first object in the opposite direction.

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

The ball on the left will stop, and the ball on the right will remain still.
The ball on the left will stop, and the ball on the right will remain still.

Both balls will swing to the right.
Both balls will swing to the right.

The ball on the right will swing to the right.
The ball on the right will swing to the right.

Both balls will swing to the left.

The correct response is:

The ball on the right will swing to the right.

When the ball on the left is pulled back and released, it will swing down and collide with the stationary ball on the right. Upon collision, due to the conservation of momentum and the equal mass of the balls, the ball on the left will transfer its momentum to the ball on the right. The left ball may come to a stop or swing back in the opposite direction, while the ball on the right will start moving to the right.

How do bumper cars at an amusement park demonstrate Newton’s third law?(1 point)
Responses

If two bumper cars collide with a certain force, then they will move away from each other in opposite directions with the same force.
If two bumper cars collide with a certain force, then they will move away from each other in opposite directions with the same force.

If two bumper cars collide with a certain force, then they will move away from each other in opposite directions with a stronger force.
If two bumper cars collide with a certain force, then they will move away from each other in opposite directions with a stronger force.

If two bumper cars collide with a certain force, then one car will transfer its force to the other car and they will move together in the same direction.
If two bumper cars collide with a certain force, then one car will transfer its force to the other car and they will move together in the same direction.

If two bumper cars collide with a certain force, then one car will transfer its force to the other car and they will move away from each other in opposite directions.

The correct response is:

If two bumper cars collide with a certain force, then they will move away from each other in opposite directions with the same force.

This statement illustrates Newton's third law of motion, which states that for every action, there is an equal and opposite reaction. When the bumper cars collide, each car exerts a force on the other, and they both move away from each other as a result of that force, demonstrating the equal and opposite reaction.

An octopus propels itself through the water by ejecting water through a funnel in its body. How does this demonstrate Newton’s third law?(1 point)
Responses

When the octopus ejects the water out, the water acts with an equal force on the surrounding water in the same direction.
When the octopus ejects the water out, the water acts with an equal force on the surrounding water in the same direction.

When the octopus ejects the water out, the water acts with an equal force on the surrounding water in the opposite direction.
When the octopus ejects the water out, the water acts with an equal force on the surrounding water in the opposite direction.

When the octopus ejects the water out, the water acts with an equal force on the octopus in the same direction.
When the octopus ejects the water out, the water acts with an equal force on the octopus in the same direction.

When the octopus ejects the water out, the water acts with an equal force on the octopus in the opposite direction.

The correct response is:

When the octopus ejects the water out, the water acts with an equal force on the octopus in the opposite direction.

This statement reflects Newton's third law of motion, which states that for every action, there is an equal and opposite reaction. When the octopus pushes water out of its funnel (action), the water pushes back against the octopus with an equal force in the opposite direction (reaction), propelling the octopus forward.
