I performed an experiment in which a mass was hung from a spring. I want to refer to the mass of the mass hung from said spring, but that leads to quite a few awkward sentences. I cannot refer to the mass as a weight, since masses and weights are two different things. Is there some alternate way of saying "The mass of the mass"?

    Just call it something other than "the mass," such as "the mass of the object"?

This is usually simply avoided

The mass of the mass is 10 kg.

can be

The mass is 10 kg.

It's a contextual problem. They used to refer to a computer case and it's insides as a CPU which was confusing if you wanted to mention the CPU chip in the same context. In any one context it's best if X means only one thing.


The mass of the suspended "object." The problem here is of course that mass means something very specific in physics. For example, in common language usage, I might say "there is a mass of vomit on the bathroom floor." In that usage, I'm not particularly interested in knowing precisely what it's mass is.

  • Hmm... I suppose I could use that, but in a sense I'm giving up precision of language when using "object" instead of "mass". Commented Dec 6, 2015 at 18:23
  • I do "get" the problem...your mass and spring are intended to be physical-world representations of components of a math equation...so you like to use unit terms that directly translate.
