Aristotle taught that all motions are due to the nature of the moving object or due to a. An object will not move unless subjected to a force. Nicolaus copernicus (1473-1543) formulated his theory of the moving earth. Reasoned that the simplest way to account for the observed motions of the sun, moon, and planets through the sky was to assume that earth circles around the sun. The balls went to rest not because of nature but because of friction. The property of things to resist changes in motion. Galileo stated that in the absence of a force, a moving object will continue moving. Law of inertia straight line unless acted on by a nonzero net force.
