The three laws of motion were first compiled by Isaac Newton in his PhilosophiÃ¦ Naturalis Principia Mathematica (Mathematical Principles of Natural Philosophy), first published in 1687. Newton used them to explain and investigate the motion of many physical objects and systems. For example, in the third volume of the text, Newton showed that these laws of motion, combined with his law of universal gravitation, explained Kepler's laws of planetary motion.
Galileo discovered the law during the first decade of the seventeenth century, but in fact he did not understand the law in the general way we have formulated it here. The general formulation of the law of inertia was devised by Galileo's pupils and by Descartes-a French philosopher, mathematician and physicist. This law is also the first of Newton's three laws. Up to the time of Galileo, it was thought that one must exert force in order to cause and preserve motion, as claimed by the physics of Aristotle. Indeed, when we look at the world surrounding us, we see that in order to continue movement we must exert force.
