Abstract
We discuss some mathematical and philosophical aspects connected with the free fall question according to the aristotelian and galileian point of view. In particular we deal with the question of the mass dependence of the fall velocity. Identifying the aristotelian velocity with a limit velocity in a resistive medium, the dispute focuses on the role of continuous functions and the two different approaches recreate in the different order of taking limits for the motion in a vacuum.
Sunto
Si propongono alcune considerazioni sui modelli matematici impliciti nel punto di vista aristotelico e galileiano sulla questione della dipendenza dalla massa della velocità di caduta dei gravi. Identificando la velocità di caduta aristotelica con una velocità limite in un mezzo resistente, la controversia si cristallizza nel ruolo delle funzioni continue, ricomponendosi nel diverso ordine di passaggio al limite nei due differenti approcci nel considerare la possibilità di moto in uno spazio vuoto
