Inertia as a measure of mass vs Impetus as a measure of momentum
" wrote in message . .. "Donald G. Shead" wrote in message m... Inertia, and/or mass is the ratio of the net force [f] exerted on and/or by an object; body, or mass of material substance to the time rate of change in the motion [s/t²] that it causes: That is mass and/or inertia are constants; so that at any given (instant) point in time the ratios w/g, and 2ft²/s are equal constants! Mass is the amount of matter in an object. It is not a ratio of anything. Nicholas How about inertia Nicholas? Is that the amount of matter in an object too?

I wasn't referring to inertial mass only to standard mass which, from your post, you seemed to be saying was a measurement of a ratio and not a physical measurement. Inertia and mass aren't the same, and they shouldn't be used interchangably the way you appear to. Inertia and momentum on the other hand... Nicholas
