Action Reaction Pairs Test

Front

What is Newton's Third Law of Motion?

Back

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

Front

What unit is used to measure force?

Back

Newton (N)

Front

If a book exerts a downward force of 5N on a table, what force does the table exert on the book?

Back

5N upward.

Front

Why can't we see the Earth move when we jump?

Back

The Earth has much more mass than we do, so its movement is imperceptible.

Front

When a swimmer pushes backward against the water, what direction does the water push them?

Back

Forward.

Front

What happens when you push an object?

Back

The object pushes back with an equal and opposite force.

Front

What is the relationship between mass and force in Newton's Second Law?

Back

Force equals mass times acceleration (F = ma).

Front

What is an example of an action-reaction pair?

Back

A person walking pushes backward on the ground, and the ground pushes forward on the person.

Front

What does it mean when we say a table has no force?

Back

It means the table does not exert a force on its own; it reacts to forces applied to it.

Front

How does mass affect the motion of an object?

Back

Greater mass requires more force to achieve the same acceleration.
