Mar 09, 2016 · This formula indicates one important physical consequence of angular momentum: because the above formula can be rearranged to give v = L / and L is a constant for an isolated system, the velocity v and the separation r are inversely correlated. Thus, conservation of angular momentum demands that a decrease in the separation r
