Newton's Law of Motion

Newton’s First Law of Motion

an object at rest will rest will remain at rest unless acted upon by a nonzero net force. An object moving at a constant velocity will continue moving at a constant velocity unless acted upon by a nonzero net force.

Inertia

Resistance to change in motion.

Newton’s Second Law of Motion

an object’s acceleration depends on its mass and on the net force acting on it.

Newton’s Third Law of Motion

if one object exerts a force on another object, then the second object exerts a force of equal strength in the opposite direction on the first object. (every action has an equal opposite reaction)
