Incorporating the effective speed of light, rather than the conventional constant c, to the four-velocity vector leads to a more physically meaningful expression for the momentum and energy of stationary objects in Schwarzschild spacetime. It indicates that free-falling objects do not gain any energy in the gravitational field; instead, they experience a conversion of rest energy into kinetic energy within the specific spacetime structure. This novel approach enables us to derive a comprehensive formulation of gravitational effects within the Schwarzschild geometry.
