Front

What does Newton's Third Law state?

Back

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

Front

When a person steps out of a boat onto a dock, what happens to the boat?

Back

The boat moves backward as the person moves forward.

Front

What is the relationship between action and reaction forces according to Newton's Third Law?

Back

Action and reaction forces are equal in magnitude and opposite in direction.

Front

What happens when you lean against a wall?

Back

The force you exert on the wall is equal to the force the wall exerts back on you.

Front

What is meant by 'force always comes in pairs'?

Back

For every force exerted, there is a corresponding force that is equal in size and opposite in direction.

Front

Can you give an example of Newton's Third Law in everyday life?

Back

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

Front

What is an example of an action-reaction pair?

Back

A swimmer pushes water backward (action), and the water pushes the swimmer forward (reaction).

Front

How does Newton's Third Law apply to rocket propulsion?

Back

Rockets expel gas backward (action), and the gas pushes the rocket forward (reaction).

Front

What is the significance of the phrase 'equal and opposite' in Newton's Third Law?

Back

It emphasizes that forces are always balanced and act in pairs.

Front

In the context of Newton's Third Law, what does 'equal' refer to?

Back

The magnitudes of the action and reaction forces are equal.
