The discussion of Earth as a system with Q, but which is not resonant, is a more extreme case than the CONICAL PENDULUM.
The conical pendulum has a simple form of a weight on a string, instead of oscillating in one plane as a conventional pendulum, it swings around in a circular orbit in the horizontal plane. It has a definite resonant frequency. Now a simple pendulum oscillates kinetic energy and potential energy, but a conical pendulum has constant potential energy and oscillates its energy from North-South energy to East-West energy. I believe that a conical pendulum still has the circular error associated with amplitude. But will it be as good a time keeper as the simple pendulum? A curious fact about the conical pendulum is that whereas the simple pendulum has earth rotation forces that show in the Foucault Pendulum, the conical pendulum has a different period depending whether is swings clockwise or anticlockwise due to the earths rotation. What do you think?
