In this paper we present modified Einstein gravitational field equations with an additional term in the energy‐momentum tensor, which leads, in the weak gravity limit, to a potential‐dependent mass density. The change in the rest mass of a gravitating body due to its field is discussed in the framework of classical Maxwell‐like gravitational theory.
Keywords: mass, modified Einstein equations, field theory of gravitation, negative gravitational energy
