WebKepler’s 2nd Law:A quick and simple derivation Angular momentum, at any time: J = MplV r = const. Thus: V r = const. (this is also an “adiabattic invariant”) Element of area swept: dA = V r dt Sectorial velocity: dA/dt = V r = const. Independent of Mpl ! It is a consequence of the conservation of angular momentum. In 1601, Johannes Kepler acquired the extensive, meticulous observations of the planets made by Tycho Brahe. Kepler would spend the next five years trying to fit the observations of the planet Mars to various curves. In 1609, Kepler published the first two of his three laws of planetary motion. The first law states: The orbit of every planet is an ellipse with the sun at a focus.
