Philosophiæ Naturalis Principia Mathematica Revision IV - Volume II: Laws of Orbital Motion (the laws and formulas)

Volume 2 (the mathematics) Colour Images] for those with an interest in the mathematical laws of orbital motion and their practical use. This volume includes all the mathematical formulas for Isaac Newton's laws of orbital motion fully described and explained, along with their applicability to planetary spin, core pressure, earth's magnetic field and the atom, together with tabulated calculation results. It also includes formulas that are unknown today such as; centrifugal force in elliptical orbits, Newton's constant of proportionality, orbital velocity and acceleration.
