mass
mass Measure of the quantity of matter in an object. The standard unit of mass is the kilogram (one kg = 1000 grams). Scientists recognize two types of mass. The
gravitational mass of a body is determined by its mutual attraction to another reference body, such as the Earth, as expressed in Newton's law of
gravitation. Spring balances and platform balances proved a measure of gravitational mass. The
inertial mass of a body is determined by its resistance to a change in state of motion, as expressed in the second law of motion.
Inertia balances provide a measure of inertial mass. According to
Einstein's principle of equivalence, upon which his general theory of
relativity is based, the inertial mass and the gravitational mass of a given body are equivalent. See also
