... m2 >> m1 : In this case, m1 is negligible compared to m2. If we let m1 = 0 in the formula, we get m1 a = (m2 /m2 )g = g, which makes sense, since with only one mass, we have freefall. m2 << m1 : This time m2 is negligible compared to m2 m1, and if we let m2 = 0 in the formula, we get a = (-m1 /m1 )g ...
