ShareMass is a property of a physical object that quantifies the amount of matter it contains.
Unlike weight, the mass of something stays the same regardless of location.
Mass is a central concept of classical mechanics and related subjects, and there are several forms of mass within the framework of relativistic kinematics.
In the theory of relativity, the quantity invariant mass, which in concept is close to the classical idea of mass, does not vary between single observers in different reference frames.
In classical mechanics, there are three types of mass or properties called mass: Inertial mass; passive gravitational mass; and active gravitational mass.
Although inertial mass, passive gravitational mass and active gravitational mass are conceptually distinct, no experiment has ever unambiguously demonstrated any difference between them.
