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 acting on two different objects, where one force is the action and the other is the reaction.

What happens when a rocket expels gas?

Back

The rocket moves in the opposite direction of the expelled gas due to Newton's Third Law.

Front

What is 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

How does a jet ski move forward?

Back

The water is pushed backward by the jet ski, causing the jet ski to move forward.

Front

What force does a tennis ball exert on a racket when hit?

Back

The tennis ball exerts an equal force on the racket as the racket exerts on the ball.

Front

What is the relationship between action and reaction forces?

Back

They are equal in magnitude and opposite in direction.

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

What does it mean when forces are balanced?

Back

The net force is zero, and there is no change in motion.

Front

What does it mean when forces are unbalanced?

Back

The net force is not zero, causing an object to accelerate.
