Newton's Third Law Review

Front

What does Newton's Third Law state?

Back

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

Front

What are action-reaction pairs?

Back

Forces that two objects exert on each other that are equal in size and opposite in direction.

Front

Do action-reaction force pairs cancel each other out?

Back

No, they do not cancel each other out because they act on different objects.

Front

What is the relationship between the forces in an action-reaction pair?

Back

The forces are equal in magnitude but opposite in direction.

Front

In the context of Newton's Third Law, what is an example of an action force?

Back

A person pushing against a wall.

Front

In the context of Newton's Third Law, what is an example of a reaction force?

Back

The wall pushing back against the person.

Front

What happens to the motion of an object when an action force is applied?

Back

The object will accelerate in the direction of the net force.

Front

What is meant by 'equal and opposite' in Newton's Third Law?

Back

It means that the forces are the same size but act in opposite directions.

Front

How does Newton's Third Law apply to a rocket launch?

Back

The rocket pushes down on the ground (action), and the ground pushes the rocket upward (reaction).

Front

What is the significance of the direction of forces in action-reaction pairs?

Back

The direction indicates that the forces act on different objects, preventing cancellation.
