Pendulum clocks - the usual electronic movement type (battery feedback
pulses solenoid when magnet on pendulum passes by).
My experience with these movements is that they are somewhat delicate: you
have to carefully adjust the clock movement vertically and horizontally
until the pendulum swings reliably.
However after running for several hours, sometimes the pendulum stops.
I think that I've ruled out the battery as the guilty party.
That set me to wondering: does gravity vary? If so, what are its
characteristics? Could gravity changes account for the pendulum stopping?
