::I think you're misinterpreting "impulse" as a more modern sense than Aristotle knew if you read this as about elastic collision. In any case, this section has been cited as the teaching, which Galileo sought to disprove at the Leaning Tower, that objects fell at a rate proportional to their mass. This is even mentioned in the [[Aristotle]] article here, so if you wish to argue otherwise you should raise the issue there. [[User:MelH|MelH]] 16:40, 14 October 2014 (EDT)

::::I don't believe so. In this chapter, Aristotle is arguing against the "void," a concept similar to the vacuum. He correctly notes that the medium through which a body falls affects the rate of fall by resisting its motion. He incorrectly notes that the mass also affects the rate. He concludes that in no medium (the void) an object will fall infinitely fast. This absurd conclusion proves the impossibility of the void. The "impulse" of weight is what we would call gravity, but in his physics it was a function of that weight. If you read the whole chapter, the centrality of a falling object's velocity being determined by its mass is quite clear. [[User:MelH|MelH]] 17:54, 14 October 2014 (EDT)
