Newton’s law states that for every action, there is an ________ reaction.

• unequal and opposite

• equal and similar

• stronger and opposite

• equal and opposite

Newton's 1st Law is also called the Law of ...

• Friction

• Inertia

• Unbalanced forces

• Newtons

 What is the unit called that measures force?

• weight
• meter
• Newton
• kilogram

states that if the net force acting on an object is zero, the motion of the object will not change (object in motion stays in motion, object at rest stays at rest until an outside force acts on it)

• Newton's First Law

• Newton's Second Law

• Newton's Third Law

• Newton's Fourth Law

An object's acceleration depends on its mass and on the size of the unbalanced force acting on it.

• Newton's second law of motion

• Newton's first law of motion

• Newton's third law of motion

• net force

The tendency of objects to resist changes in their state of motion.
