| Mass Story1 #722705 A general term which refers to two values intrinsic to a body: one quantifies the body's inertia (inertial mass), and the other one the body's contribution to the gravitational force (gravitational mass or gravity load). While these masses seem to be distinct, experiments have in fact verified that they were equal. Mass appears in all the calculations of classical physics. In special relativity, (invariant) mass expresses a body's energy. |
