The Theory of Impetus is a historical concept in physics that was developed in the late medieval period to explain the motion of objects. This theory emerged as an attempt to understand the reasons behind the motion of projectiles and other objects, particularly before the development of Newtonian mechanics. The impetus theory posits that when an object is set in motion, it is imparted with a quality called "impetus," which is somewhat analogous to what we might now think of as momentum.
