Building on the principle 'Distant is slow, Near is fast' (DOI: 10.5281/zenodo.20538716), we extend the Koku Universe framework to unify four classical mechanical phenomena: the lever principle, centrifugal force, centripetal force, and inertia. All four are shown to be manifestations of the temporal layer density gradient ∇τ(N). The master equation: F = ∇(1/N). Force is the spatial gradient of inverse Koku-plane layer density. Near is fast. Far is slow. The gradient between them is force. Part of TheYKHC Koku Universe Research Series.
