according to aristotle, weight was the direct cause of the falling motion of an object, the speed of the falling object was supposed to be directly proportionate to the weight of the object. as medieval scholars discovered that in practice the speed of a falling object increased with time, this prompted a change to the concept of weight to maintain this cause effect relationship. weight was split into a "still weight" or "pondus", which remained constant, and the actual gravity or "gravitas", which changed as the object fell. the concept of "gravitas" was eventually replaced by jean buridan's impetus, a precursor to momentum.
