* Linear motion is a fundamental concept: It's simply the movement of an object in a straight line. Humans have observed this type of motion since the dawn of time.
* Early philosophers and scientists: While no one "discovered" linear motion, early thinkers like Aristotle and Galileo Galilei made significant contributions to our understanding of it.
* Newton's Laws of Motion: Sir Isaac Newton formalized our understanding of linear motion with his three laws of motion, which are the basis for much of classical physics.
Instead of thinking of a single discoverer, consider the contributions of many individuals throughout history who helped us understand and define linear motion.
