Newton's 3rd Practice

Front

What is Newton's 3rd Law of Motion?

Back

Newton's 3rd Law of Motion states that for every action, there is an equal and opposite reaction.

Front

What does the Law of Action-Reaction explain?

Back

It explains that when one object exerts a force on another, the second object exerts a force of equal strength in the opposite direction.

Front

Give an example of Newton's 3rd Law in everyday life.

Back

When you jump off a small boat, you push the boat backward as you move forward.

Front

What happens when a tennis ball hits the ground?

Back

The ball exerts a force on the ground, and the ground exerts an equal and opposite force that makes the ball bounce back.

Front

How does walking demonstrate Newton's 3rd Law?

Back

When you push backward on the ground with your feet, the ground pushes you forward.

Front

What force acts on you when you jump?

Back

The floor pushes you upward, allowing you to move into the air.

Front

If a hammer hits a nail with a force of 12 N, what force does the nail exert on the hammer?

Back

The nail exerts a force of 12 N back on the hammer.

Front

What is inertia?

Back

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

Front

How does inertia relate to Newton's 1st Law?

Back

Newton's 1st Law states that an object at rest stays at rest, and an object in motion stays in motion unless acted upon by a net external force.

Front

What is an action force?

Back

An action force is the initial force exerted by one object on another.
