A law of motion that states that an object at rest stays at rest and one in motion stays in motion.

• Newton's First Law
• Newton's Second Law
• Newton's Third Law
• Newton's Fourth Law

This says the acceleration of an object increases by the force applied to it, and decreases based on its mass.

• Newton's First Law
• Newton's Second Law
• Newton's Third Law
• Law of Acceleration
