• # question_answer Kepler's second law (law of area) is nothing but a statement of A)  work energy theoremB)  conservation of linear momentumC)  conservation of angular momentum  D)  conservation of energy

From Kepler's 2nd law - The straight line joining the sun and the planet sweeps out equal areas in equal  time intervals $(\frac{dA}{dt}=$ const; area swept) Areal velocity of the satellite is given by $\frac{dA}{dt}=\frac{1}{2}\omega {{r}^{2}}=const.=\frac{L}{2m}$ where$\omega$ = angular velocity of the satellite L = mvr =$m\omega {{r}^{2}}$ = const, showing that Kepler's 2nd law is a consequence of the conservation of angular momentum.
