Conservation of angular momentum in Earth-Moon system

WebMomentum is something that we define to make sense of a physical system, but all that really matters is the actual motion is the same no matter what coordinates we choose. (I stress this point here because it often catches people off-guard that angular momentum can change even if your coordinates aren't moving.)
