Definition and Analysis of Generalized Gravitational Acceleration

Within the WQT framework, this paper defines the "shadow radius" as r = x•(c/d)•l_p, interpreting it as the effective distance reading of a world quantum on the current projective layer (x) and motion state (γ = c/d). Substituting this shadow radius into the potential energy formula V = G_x•M_x•m_p/r, we obtain V = M_x•c•d after algebraic simplification. This result is fully consistent with the essential expression of potential energy V = m_0•c•d derived in WQT, demonstrating the self-consistency of the shadow radius definition within the WQT framework. This paper specifically clarifies that the projective-layer mass reading M_x is equal to the ontological-layer rest mass m_0 (M_x = m_0): the environmental coupling factor x modulates gravitational strength only through the effective gravitational constant G_x, without altering the mass reading. This paper also analyzes the properties and physical meaning of the shadow radius.
