Re: Which came first, mass or inertia?



Help!
I figured someone out there would know these historical facts. If there
is someone who knows this please fill me in! I am isolated and have tried
asked the usual suspects, like the web...

Does anyone know if the concept of mass, as
the quantity of matter, preceded the notion of inertia? I know that
weight
has been used since the dawn o' man but what about mass?

On the same topic, does anyone know, in modern language, how Newton
introduced momentum as the "quantity of motion?" and did he derive the
Law of Conservation of Momentum and if he did, did he call it that?

Where does the word momentum come from in the strictest sense. Is this
a Newton creation also?

Thanks for the light of your wisdom!
