  1. rest mass

    Rest mass is the mass of an object as measured when it is at rest relative to an observer, regardless of its motion when observed from different inertial frames. This mass does not change with the object's speed or direction as seen by different observers. It is a fundamental property of the object, a fundamental property of the matter in the object. In the theory of relativity, it is also the mass that is used to calculate force and gravitational interactions. It is often used in conjunction with the concept of relativistic mass, which is the total energy of an object divided by the speed of light squared. The rest mass is also the source of energy described by Einstein's famous equation E=mc2. When subjected to a force, this is the mass that accelerates.
