Applying Newton's Third Law Flashcard

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 force?

Back

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

Front

What is a reaction force?

Back

A reaction force is the force exerted by the second object back on the first object.

Front

In the context of a book resting on a table, what is the action force?

Back

The weight of the book acting downward due to gravity.

Front

What is the normal force?

Back

The normal force is the support force exerted by a surface perpendicular to the object resting on it.

Front

How does a rocket launch demonstrate Newton's Third Law?

Back

The rocket's engines push exhaust gases backward, and the gases push the rocket forward.

Front

What happens when a swimmer pushes water backward?

Back

The water pushes the swimmer forward, demonstrating action and reaction forces.

Front

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

Back

A sprinter pushing off the starting blocks.

Front

What is the role of friction in action-reaction pairs?

Back

Friction can affect the motion of objects but does not change the action-reaction relationship.

Front

How does Newton's Third Law apply to walking?

Back

When you push backward on the ground, the ground pushes you forward.
