Title page of Isaac Newton's Philosophiae Naturalis Principia Mathematica, 1687, featuring large Latin text and publication details in a bordered layout. — Newton’s laws of motion The title page of Isaac Newton's *Philosophiae Naturalis Principia Mathematica* (1687; *Mathematical Principles of Natural Philosophy*), the work in which the physicist introduced his three laws of motion.

According to Newton’s second law of motion, the relationship between force, mass, and acceleration for an object with constant mass is expressed by the equation $F = m a$ , where $F$ is the net force, $m$ is the mass, and $a$ is the acceleration.12

Because acceleration is directly proportional to the net force when mass remains constant, doubling the net force applied to an object will result in the object's acceleration also doubling.12
