De Qvantitate Motus seu Impetu.
intentio motus in mobili seu viyor et ipta mobilis veloeitas.
Nam vigor est ut quotiens factus divisione impetus
per motem (per defin. 2. hic) et velocitas est ut quotiens fa-
etus divisione protractionis per volumen (per def. 2: exp. de Ve
locitate muniverrum). Et, ii nullum sit discrimen in dentitati-
bus, moles reprae sentantur per volumina (per prap. 1. cap. de
quantitate materiae) et coincidunt impetus et protractiones
per prap. 1. hio); coincidunt ergo vigor et velocitas.
