There's no such _thing_ as a weight

Y'know what? Technically speaking; when y'come right down to it, there
is no such _thing_ as a weight. What many of us have been calling
"weights", aren't. They are objects; bodies, and masses of material
matter; that exert force and weight on each other.

"Lifting weights" is a misnomer. What are actually lifted, are masses
of matter that have some specific weight.

All this hassle; for what? Masses are quantities of material matter,
and weight is the force they exert on each other. Cheeze wiz
anyways(:^))

Are you just retarded stupid or plain stupid? What on gods green earth do
you think ANYONE gained from your little diatribe above? Technically
speaking, you're not a person, you're a collection of chemicals worth about
a buck.

Well I wasn't thinking about my worth; it just dawned on me that weight
is not a _thing_, it is a force, and a force is not a thing in itself;
it's just pressure (P), divided by the area (A) upon which it bears,
and for an infinitly sharp point would be infinite. Where infinitely
sharp is practically impossible, but is something to think about.

That is precisely what is taught in physics classes
starting with grade school. The SI units for weight
are newtons, which are also the units of force.

Whether 'force' is a concrete or abstract noun seems
like a purely linguistic issue rather than belonging
to physics. As you have just discovered, it is the
latter, but what is the relevance of this discovery?

In my opinion there is such a thing called "weight". Weight is just a more
convenient term to represent the heaviness (force) of something.

Example, asking "what the force of a packet of sugar" is sounds ambiguous,
whereas asking "what the weight of a packet of sugar" is more comprehensible.

You are right, Don. We should clean up the language and call a mass a
mass! When we buy a sack fertilizer, we want to know how much mass is
there, not how much it weighs at sea level.

The use of words has evolved down from less enlightened times when
people didn't know the difference. If people knew the root meanings of
many of the words they still use today, they would be amazed at what
mumbo jumbo they are speaking!

Congratulations, Don, you have it. The property that belongs to the
physical object is mass, not weight.

Weight is the strength of the *interaction* between the object (its
mass) and another nearby massive object (usually the Earth).

Slowly, but surely, it's becoming clearer in your mind.

Don't get your water hot PD; I've known this all along: What I didn't
know was that calling a _mass_ of matter a _weight_ was wrong, Now it
remains to prove that ordinary weight scales - both balance and spring
- measure the force we call weight, and (some) torsional balances are
able to measure mass.

Whether weight is a _property_ of mass or not, remains to be seen.
