TEST PRACTICE - Newton's 1st Law

What does Newton’s Law of Motion say?

• An object at rest stays at rest, an object in motion stays in motion, unless acted on by an outside force.

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

• The force acting on an object is equal to the mass of that object times its acceleration.
