Laws of Motion

Newton's Laws of Motion

• Newton's First Law of Motion states that in order for the motion of an object to change, a force must act upon it, a concept generally called inertia.
• Newton's Second Law of Motion defines the relationship between acceleration, force, and mass.
• Newton's Third Law of Motion states that any time a force acts from one object to another, there is an equal force acting back on the original object. If you pull on a rope, therefore, the rope is pulling back on you as well.
