Newton's 3rd Law of Motion

Front

What is Newton's 3rd Law of Motion?

Back

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

How does a swimmer move forward when paddling?

Back

As the swimmer's hands push the water backward, the water pushes forward on the swimmer.

Front

What happens when you blow up a balloon and let it go?

Back

The air coming out of the back of the balloon (action) causes the balloon to move forward (reaction).

Front

What is the action/reaction pair when a tennis ball bounces off the ground?

Back

Action: tennis ball hitting the ground. Reaction: tennis ball bouncing back up.

Front

What do forces always come in?

Back

Pairs.

Front

If a bat hits a ball with a force of 100 Newtons, what is the force exerted by the ball on the bat?

Back

100 Newtons, opposite direction.

Front

What is an example of Newton's 3rd Law in everyday life?

Back

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

Front

What is the definition of action and reaction forces?

Back

Action forces are the initial forces applied, while reaction forces are the forces that occur in response, equal in size and opposite in direction.

Front

How does a rocket launch demonstrate Newton's 3rd Law?

Back

The rocket pushes exhaust gases downward (action), and the gases push the rocket upward (reaction).

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion.
