Newton's Third Law & Action-Reaction Pairs

Front

What is Newton's Third Law of Motion?

Back

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

Front

What happens when you push down on a surface?

Back

The surface pushes you up with an equal force.

Front

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

Back

When a swimmer pushes the water backwards, the water pushes the swimmer forward.

Front

What is an action-reaction pair?

Back

Two forces that are equal in size and opposite in direction, acting on two different objects.

Front

What is the reaction force when a person jumps off a skateboard?

Back

The skateboard rolls backward.

Front

How does Newton's Third Law apply to a rocket launch?

Back

The rocket pushes down on the ground, and the ground pushes the rocket upward.

Front

What is the significance of equal and opposite forces?

Back

They explain how objects interact and move in response to each other.

Front

What is an example of a force pair in everyday life?

Back

When you sit on a chair, your body exerts a downward force on the chair, and the chair exerts an upward force on your body.

Front

What does it mean when we say forces are 'always in pairs'?

Back

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

Front

What is the role of friction in action-reaction pairs?

Back

Friction can affect the motion of objects but does not change the action-reaction relationship.
