Newton's 3rd Law of Motion

Front

What does Newton's 3rd Law of Motion state?

Back

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

Front

In the context of Newton's 3rd Law, what is meant by 'action'?

Back

An action is a force exerted by one object onto another.

Front

In the context of Newton's 3rd Law, what is meant by 'reaction'?

Back

A reaction is the force exerted back on the first object by the second object.

Front

How does Newton's 3rd Law apply when a person jumps off a skateboard?

Back

The force that propels the person forward results in an equal force pushing the skateboard backward.

Front

What is an example of Newton's 3rd Law in everyday life?

Back

When you push against a wall, the wall pushes back with an equal force.

Front

What happens to a boat when a person steps off it onto a dock?

Back

The boat moves backward as the person moves forward due to the action-reaction principle.

Front

What is the relationship between action and reaction forces?

Back

They are equal in magnitude and opposite in direction.

Front

How does a book resting on a table illustrate Newton's 3rd Law?

Back

The book exerts a downward force on the table, and the table exerts an equal upward force on the book.

Front

What is the significance of Newton's cradle in demonstrating Newton's 3rd Law?

Back

It visually shows how action and reaction forces work through the transfer of momentum.

Front

Can action and reaction forces act on the same object?

Back

No, action and reaction forces act on different objects.
