The pendulum's period isn't affected by its bob mass at all, in the simple models of a pendulum, only length from axle to center of mass of the bob.
I invite an armchair physics teacher to explain why this is different. Probably something to do with shifting the center of mass closer to the axle.
- makomk 11y agoYeah. They're actually putting them on a shelf a fair way up the pendulum itself, so I imagine that adding them shifts the center of mass noticeably. (Though we're talking single-digit parts per million corrections here, so they don't need to shift it by a huge amount.)
