I use GeoGebra to construct mechanical motion of M2. Two curves comprise a Curved Space Division Assembly (CSDA). A unit circle is Gfield potential and contains M1 mass/volume. A unit parabola (r unit circle = (p) initial focal radius placed @ (pi/2) spin direction. M2 energy can be metered on curved diagonal in space time square constructed with M2 orbit parameters (r, f(r)). The curved diagonal of the square has a complete history of orbit curves. (r) Sir Isaac Newton's displacement radius as abscissa and f(r) energy of displacement as ordinate.

Can't add geometry attachments?
