\[ v_{\mathrm{rel}} = \dot{x} - v \] \[ v_{\mathrm{rel}} > 0 \;\vee\; \bigl(v_{\mathrm{rel}} = 0 \;\wedge\; kx > f_s N\bigr) \;\Rightarrow\; m\ddot{x} + kx = -f_d N \] \[ v_{\mathrm{rel}} < 0 \;\vee\; \bigl(v_{\mathrm{rel}} = 0 \;\wedge\; kx < -f_s N\bigr) \;\Rightarrow\; m\ddot{x} + kx = +f_d N \]

\[ v_{\mathrm{rel}} = 0 \;\wedge\; k|x| \le f_s N \quad\Rightarrow\quad \dot{x} = v \]
