This is UFT360 Sections 1 and 2 on the generally covariant inverse square law for all orbits, two dimensional and three dimensional: the acceleration due to gravity is the Lagrange derivative of the orbital velocity. The Lagrange or convective derivative is that in a moving frame of reference defined by astronomical observations of the orbits. Example moving frames of reference are given which can be graphed and numerically analyzed.
