Newton's 3rd Law

Front

What is Newton's 3rd Law of Motion?

Back

For every action, there is an equal and opposite reaction.

Front

What are action-reaction forces?

Back

Forces that occur in pairs; when one object exerts a force on another, the second object exerts an equal and opposite force back.

Front

Can action-reaction forces cause a change in motion?

Back

Yes, they can cause a change in motion when they act on different objects.

Front

What happens when a man pushes against a wall?

Back

The man exerts a force on the wall, and the wall exerts an equal and opposite force back on the man.

Front

Do action-reaction forces cancel each other out?

Back

No, they do not cancel each other out because they act on different objects.

Front

What is an example of action-reaction forces in everyday life?

Back

When you jump off a small boat, you push the boat backward while moving forward.

Front

What is the action when a rocket launches?

Back

The rocket engines push down on the ground.

Front

What is the reaction when a rocket launches?

Back

The ground pushes the rocket upward with an equal and opposite force.

Front

If a small car pushes a big truck, what happens?

Back

The truck applies an equal and opposite force on the car.

Front

What is the relationship between action and reaction forces?

Back

They are equal in strength but opposite in direction.
