Abstract
According to Ibn Sina (Avicenna), in the forced movement of the moving object (projectile motion), the moving object acquiring the potency or inclination from the first mover continues motion until this force gradually diminishes and comes to a stop. Although this theory was first proposed by Philoponus, with the modifications Ibn Sina made, this theory has been called “Mayl Theory”. This theory is important in the history of science. This article, comparing the concept of inclination with the concepts of Newtonian mechanics, concludes that the concept of inclination does not correspond to any of the Newtonian mechanic concepts such as force, kinetic, momentum or inertia.
