Special emphasis is placed in two exact physical analogies: the analogy based on inertial fields from the so-called \"1+3 formalism\", and the analogy based on tidal tensors. Both are reformulated, extended and generalized. We write in both formalisms the Maxwell and the full exact Einstein field equations with sources, plus the algebraic Bianchi identities, which are cast as the source-free equations for the gravitational field.
