However, Newton's theorem of revolving orbits states that the angular speeds are related by multiplication: ω 2 = kω 1, where k is a constant. Combining these two equations shows that the angular speed of the precession equals Ω = (k − 1)ω 1. Hence, Ω is constant only if ω 1 is constant.
Newton derived an early theorem which attempted to explain apsidal precession. This theorem is historically notable, but it was never widely used and it proposed forces which have been found not to exist, making the theorem invalid. This theorem of revolving orbits remained largely unknown and undeveloped for over three centuries until 1995. [14]
Theorem 3 now evaluates the centripetal force in a non-circular orbit, using another geometrical limit argument, involving ratios of vanishingly small line-segments. The demonstration comes down to evaluating the curvature of the orbit as if it were made of infinitesimal arcs, and the centripetal force at any point is evaluated from the speed ...
Illustration of Newton's theorem of revolving orbits. The green planet completes one (subharmonic) orbit for every three orbits of the blue planet ( k =1/3). A GIF version of this animation is found here .

Social Security’s annual cost-of-living adjustment (COLA) helps keep retirees afloat as inflation erodes purchasing power. But this year, it’s sparking some anxiety.
