| contents | <p><strong><span lang="EN-US">Abstract.</span></strong><span lang="EN-US"> The equivalence principle is a foundational element of relativistic gravitation, yet its precise structural implications are often obscured by the distinction between geometric and energetic descriptions. In this paper, we examine the equivalence principle as a principle of <em>structural correspondence</em>: it identifies which features of relativistic kinematics must be shared between inertial motion and gravitation. We show that when described relative to a global coordinate time—the natural variable for energy conservation—the equivalence principle enforces a universal "additive" scaling structure. In this view, gravitational potential and kinematic motion enter the relativistic line element as parallel, subtractive contributions to the proper time budget. This perspective reconciles the "multiplicative" time dilation factors of standard pedagogy with a unified, norm-like energy conservation law. From this standpoint, gravitational time dilation and the associated relativistic mass–energy scaling emerge not merely as geometric consequences, but as necessary structural features of a unified energy budget. This formulation is shown to be dynamically consistent with General Relativity, reproducing the correct orbital precession provided the kinematic term is parameterized by coordinate velocity.</span></p> |
