Copernicus, Kepler, Tycho, and Galileo together gave us a new way of looking at the motions in the heavens, but they could not explain why the planets move they way the do. It was to be the work of Isaac Newton who was to sweep away the last vestiges of the Aristotelian view of the world and replace it with with a new, vastly more powerful predictive synthesis, in which all motions, in the heavens and on the Earth, obeyed three simple, mathematical laws of motion. This lecture introduces Newton's Three Laws of Motion and their consequences. Recorded 2007 Oct 12 in 1000 McPherson Lab on the Columbus campus of The Ohio State University.
