VELOCITY AND REST AS PHYSICALLY ENFORCED CONDITIONS

This paper examines velocity and rest not as abstract kinematic labels but as physically realizable states that must be enforced in any finite material system. It shows that for an extended system to possess a definite velocity or rest state, internal degrees of freedom must remain coherently constrained despite finite signal propagation and the absence of perfect rigidity. External interactions redistribute momentum locally, requiring internal coupling to suppress relative divergence among components. Rest is treated as a special case of this same enforcement, not as the absence of physical activity. The paper demonstrates, using mechanism-first reasoning compatible with relativity, that both velocity and rest exist only as maintained physical regimes and cannot arise as passive or unconstrained states.
