最佳解答:
Einstein mass-energy relationship e stand for the energy released in a nuclear reaction m stand for the mass defect in nuclear reaction c is light speed Mass–energy equivalence is the concept that the mass of a body is a measure of its energy content. In this concept, mass is a property of all energy; energy is a property of all mass; and the two properties are connected by a constant. This means (for example) that the total internal energy E of a body at rest is equal to the product of its rest mass m and a suitable conversion factor to transform from units of mass to units of energy.
