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 does it mean when we say 'equal and opposite forces'?

Back

It means that when one object exerts a force on a second object, the second object exerts a force of equal magnitude but in the opposite direction on the first object.

Front

In the context of Newton's 3rd Law, what happens when a person steps out of a boat?

Back

As the person steps forward onto the dock, the boat moves backward due to the equal and opposite reaction.

Front

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

Back

When you jump off a small boat onto a dock, the boat moves backward as you move forward.

Front

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

Back

The force of gravity pulls the book down, while the table exerts an equal and opposite force upward, preventing the book from falling.

Front

What is the net force when two equal forces act in opposite directions?

Back

The net force is 0 because the forces cancel each other out.

Front

What is another name for Newton's 3rd Law?

Back

The Law of Action and Reaction.

Front

How can you demonstrate Newton's 3rd Law using a balloon?

Back

When air rushes out of a balloon, the balloon moves in the opposite direction.

Front

What role does friction play in Newton's 3rd Law?

Back

Friction can affect the motion of objects, but it does not change the action-reaction pairs described by Newton's 3rd Law.

Front

Can you give an example of Newton's 3rd Law in sports?

Back

When a swimmer pushes against the water, the water pushes back with an equal and opposite force, propelling the swimmer forward.
