Newtons_Laws_of_Motion

The three basic postulates of Isaac Newton from which Classical Mechanics is derived.

Newton's First Law: "Every body continues travels in a straight line with constant speed unless acted on by a force"

Newton's Second Law: "The rate of change of a body's momentum is proportional to the force acting on it"

Newton's Third Law: "If body A exerts a force on body B, then body B exerts a force of equal magnitude and opposite direction on body A" or more commonly "For every action, there is an equal and opposite reaction"
