What were the views of Greek philosopher Aristotle about the state of motion?
Asked by Topperlearning User | 29th May, 2014, 05:45: PM
According to Aristotle's law of motion, an external force is necessary to keep a body in motion. However, Aristotle was proved to be wrong by Galileo. It was observed that the external forces were necessary to counter the opposing forces of friction to keep bodies in uniform motion. If there were no friction, no external force would be needed to maintain the state of uniform motion.
