Physics Test Review

Match the following description of one of Newton's Laws to the name of the law.

• The force needed to move an object is equal to the mass of the object times acceleration.

• Newton's Third Law

• For every action, there is an equal & opposite reaction.

• Newton's Second Law

• Objects in motion stay in motion, and objects at rest stay at rest unless a force acts upon them.

• Newton's First Law
