Note: Mass and weight are often used, in a general way, as
interchangeable terms, since the weight of a body is
proportional to its mass (under the same or equal
gravitative forces), and the mass is usually
ascertained from the weight. Yet the two ideas, mass
and weight, are quite distinct. Mass is the quantity of
matter in a body; weight is the comparative force with
which it tends towards the center of the earth. A mass
of sugar and a mass of lead are assumed to be equal
when they show an equal weight by balancing each other
in the scales.
