The LRL vector A is constant in length and direction, but only for an inverse-square central force. For other central forces, the vector A is not constant, but changes in both length and direction. If the central force is approximately an inverse-square law, the vector A is approximately constant in length, but slowly rotates its direction. A generalized conserved LRL vector A can be defined for all central forces, but this generalized vector is a complicated function of position, and usually not expressible in closed form.
