When Newton invented mass |
I wonder what Newton was thinking of when he invented mass as being the
product of a body's density and weight; conjointly?
That would mean mass is the product of a body's weight and its volume,
wouldn't it?

AARRRRRGGGGGGGHHHHHHHHHHHH!!!!!!!!!!!!!!!!!!!!!!
How could Newton, or anybody else **INVENT** a fundamental property of
matter????
You FRIGGING IDIOT!!

After several years, Don has still not grasped seventh-grade physics
and wrote:

Read your physics book again, Don:
Density = Mass / Volume
Ain't no weight in there...

He did it to confuse you.
It worked - even after several years you still don't show any hope of
ever understanding.

Mass is defined as a measure of inertia, and i belive it was Galileo
that came up with it, not Newton. And mass is not the product of weight
and its volume. Weight is a force, kg m s^-2. Multiplying by volume,
m^3, gives someting i am not sure what it is. Then you say the product
of density and weight which is wrong again. Had you said density times
volume it would have been right; density is defined as mass per volume.
Exactly where did you learn physics, and where did you get these
definitions? Don't tell me Plutonium taught you physics.

Galileo Galilei--Although inertial mass, passive gravitational mass and
active gravitational mass are conceptually distinct, no experiment has
ever unambiguously demonstrated any difference between them. One of the
consequences of the equivalence of inertial mass and passive
gravitational mass is the fact, famously demonstrated by Galileo
Galilei, that objects with different masses fall at the same rate,
assuming factors like air resistance are negligible. The theory of
general relativity, the most accurate theory of gravitation known to
physicists to date, rests on the assumption that inertial and passive
gravitational mass are completely equivalent. This is known as the weak
equivalence principle. Classically, active and passive gravitational
mass were equivalent as a consequence of Newton's third law, but a new
axiom is required in the context of relativity's reformulation of
gravity and mechanics. Thus, standard general relativity also assumes
the equivalence of inertial mass and active gravitational mass; this
equivalence is sometimes called the strong equivalence principle.

He was thinking of a mugful of frothy beer. Conjointly.
