Unit 3 Force - 3rd Law

Front

What is Newton's Third Law of Motion?

Back

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

Front

If a man and an elephant push on each other, which one is capable of more force?

Back

The elephant is capable of more force due to its greater mass.

Front

When two objects interact, how do the forces they exert on each other compare?

Back

They exert equal and opposite forces on each other.

Front

True or False: Newton's Third Law of Motion applies only to moving objects.

Back

False. It applies to all objects, regardless of their motion.

Front

If I push on a table with 25 N of force and it doesn't move, how hard does the table push back on me?

Back

The table pushes back with 25 N of force.

Front

What happens to the forces when two astronauts play catch in space?

Back

Joe and the ball put an equal amount of force on each other.

Front

Define action-reaction pairs in the context of Newton's Third Law.

Back

Action-reaction pairs are two forces that are equal in size, opposite in direction, and act on different objects.

Front

What is the significance of mass in determining force capability?

Back

Greater mass results in a greater capability to exert force, as per Newton's Second Law (F=ma).

Front

How does friction affect the application of Newton's Third Law?

Back

Friction can affect the net force acting on an object, but the action-reaction forces remain equal and opposite.

Front

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

Back

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