Avocenna's Theory of Motion

Avocenna considered and rejected various answers to this question before formulating his own theory. The story told by Avocenna has seemed exciting to historians of science because it sounds quite a lot like modern impetus theory. Once something is set in motion, it will continue unless it is prevented or slowed by something else. Abul Barakat's new and unfamiliar physical theories sound rather… well, familiar. Broadly speaking these views sound what we found with Kreskis.
