There are some things that we might say that will commit us: For
example if we say that a body's mass is the ratio of its weight (w),
divided by the acceleration (g) at which it will free fall; which is
equal to the ratio of the net force (f) exerted on and/or by it,
divided by the acceleration (a) that is caused: Then - for better or
worse - we are committed to this statement; so that in all future use
of "mass" we must include the entire contents of the statement.

We cannot say f=ma, or w=mg, because m=w/g=f/a: We must use w/g or f/a;
not m; as f=fa/a, or f=wg/a, or w=wg/a. That's my two cents worth.

Because we can't use only part of the complete statement; that defines

Because (m)=w/g=f/a, f=(m)a, and w=(m)g!

so you have a simple scalar re-formulation of Newtons 2nd, so what?

Hardly Jeremy: According to Newton's 2nd: f=kma; but (m)=w/g=f/a; so
f=k(m)a! Can't you even get that right(;^?

fundamental

What is invariable Jeremy is the _ratio_ of the variable force (f)
divided by the variable acceleration(a); that are proportional to each
other, and numerically equal for any given body:

mass"
Can't you all see that?
