Front

What is Newton's Third Law of Motion?

Back

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

Front

When you lean on a wall, what can be said about the forces involved?

Back

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

Front

What are action-reaction pairs?

Back

Forces that two objects exert on each other that are equal in size and opposite in direction.

Front

Can action-reaction pairs cause a change in motion?

Back

Yes, they can cause a change in motion.

Front

What happens when a cannon fires a cannonball?

Back

The cannon exerts a force on the cannonball, and the cannonball exerts an equal and opposite force on the cannon.

Front

What is an example of an action-reaction pair?

Back

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

Front

If object A exerts a force on object B, what does object B do?

Back

Object B exerts an equal and opposite force on object A.

Front

What does 'equal and opposite' mean in Newton's Third Law?

Back

It means that the forces are the same in strength but act in opposite directions.

Front

What is the significance of the term 'reaction' in Newton's Third Law?

Back

It refers to the force that is exerted in response to an action force.

Front

How does friction relate to Newton's Third Law?

Back

Friction is a force that can act as an action or reaction force depending on the interaction between surfaces.
