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 is an action-reaction pair?

Back

A pair of forces that are equal in size, opposite in direction, and act on two different objects.

Front

If a bat hits a ball with a force of 100 Newtons, what force does the ball exert on the bat?

Back

100 Newtons, opposite direction.

Front

What happens when a cannon fires a cannonball?

Back

The cannonball exerts a force on the cannon, causing it to move backward.

Front

When a flyboarder pushes down on the water, what does the water do?

Back

The water pushes up against the flyboard.

Front

What is an example of Newton's Third Law in sports?

Back

When a tennis ball is hit with a racket, both the ball and racket exert equal forces on each other.

Front

What is the reaction force when a swimmer pushes the water backwards?

Back

The water pushes the swimmer forward.

Front

How do action-reaction pairs relate to motion?

Back

They explain how forces interact and cause changes in motion.

Front

What is the significance of the direction of forces in action-reaction pairs?

Back

The forces are always equal in magnitude but opposite in direction.

Front

Can action-reaction forces cancel each other out?

Back

No, they act on different objects and do not cancel each other.
