Most of you already know that the weight of a 16 ounce pint of most
water like liquids varies at various locations. This is for those who
may not know that it does or why it does:
The weight of a fluid pint here on Earth is about one pound, or 16
ounces; but only where it will free fall at a rate of g/2=16'/sec^2*,
which is the approximate rate of free fall due to gravity over most of
Earth's surface: Therefore the "quantity of matter", or mass in one
fluid pint numerically equals g/2=16 oz/(16'/sec^2)=1 oz sec^2/foot.
In an environmentally controlled laboratory on the moon, a fluid pint
will only weigh about one sixth of a pound, or about 2.67 ounces:
Because the rate of free fall (g/2) due to gravity there is only about
one sixth as great as it is on Earth: So that g/2=2.67'/sec^2. The
"quantity of matter", or mass in one fluid pint there is still
numerically equal to 2.67 oz/(2.67'/sec^2)=1 oz sec^2/foot; the same as
it was on Earth.
In an environmentally controlled laboratory on any similar planet with
a solid stable surface, the quantity of matter, or mass in a fluid pint
will still be 1 oz sec^2/foot: Because its weight (w), divided by the
rate of free fall (g/2) due to gravity there will still be 1 oz
This can be put into a simple mathematical formula as (m)=2w/g=2f/a= _A
Constant_ :: So that f=2(m)g=2(m)a ....
*Notice that this _rate_ is only one half of the _acceleration_ due to
