Unit 6: Newton's Second Law of Motion Quiz

What does Newton's Second Law of Motion state?

• The acceleration of an object is dependent upon the net force acting upon it and the mass of the object.

• An object at rest stays at rest.

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

• Objects in motion stay in motion.
