Newton's 3rd Law of Motion

Front

What does Newton's 3rd Law of Motion state?

Back

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

Front

What is the significance of Newton's cradle in demonstrating Newton's 3rd Law?

Back

It visually shows that when one ball is lifted and released, it strikes the others, demonstrating action and reaction.

Front

What is the unit of measurement for force?

Back

Newton (N) is the unit used to measure force.

Front

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

Back

The ball exerts a force of 100 Newtons in the opposite direction.

Front

What is an example of action and reaction forces in everyday life?

Back

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

Front

How does Newton's 3rd Law apply to rocket propulsion?

Back

Rockets push exhaust gases downward (action), and the rocket moves upward (reaction).

Front

What is inertia, and how does it relate to Newton's 1st Law?

Back

Inertia is the tendency of an object to resist changes in its state of motion, as described by Newton's 1st Law.

Front

What is the difference between mass and weight?

Back

Mass is the amount of matter in an object, while weight is the force of gravity acting on that mass.

Front

What is an example of equal and opposite forces?

Back

A person sitting in a chair exerts a downward force equal to the upward force exerted by the chair.

Front

What happens to the forces when two objects collide?

Back

The forces they exert on each other are equal in magnitude and opposite in direction.
