In common usage, however, people may also use the term "inertia" to refer to an object's "amount of resistance to change in velocity" (which is quantified by its mass), and sometimes its momentum, depending on context (e.g. "this object has a lot of inertia"). The term...

Notes on figure illustrating ballistic trajectory of impetus theory vs. Aristotelian theory: With impetus theory, angels are not needed to push celestial spheres. With an initial impetus, spheres would keep moving since there is no air resistance in the celestial realm.

The theory of impetus was set forth by the Parisian philosopher Jean Buridan. It was based on observations about the motion of objects that had been made by the Greek writer John Philoponus in the sixth century A.D. John's intellectual sense was on the right track, but he never fully developed the reason why it should be as...

of Paris, he was a follower of William of Occam and a nominalist. Buridan promoted the theory of impetus, arguing that a projectile continues in motion not, as Aristotle held, because it is supported by the surrounding air, but because of the force transmitted to it by the object that launched it.

The Physics commentary contains an array of examples of innovative and damagingly critical commentary. One of the most celebrated achievements is the theory of impetus, Concepts akin to those deployed in Philoponus' impetus theory appear in earlier writers such as Hipparchus (2nd c. BCE) and Synesius (4th c.
