Re: Saturday Clock Blogging (none / 0)

Is it possible to create an pseudo-infinite motion pendulum using magnets, or does the motion wear out quickly because of wear and tear? Just thought I'd write a question that sounded pro ;)

Re: Saturday Clock Blogging (4.00 / 2)

A pendulum is just a falling weight. It's constrained in such a way that when it reaches the bottom of it's fall, it raises up almost as far in the opposite direction. A heavy pendulum with a good suspension will keep running by itself in diminishing arcs for hours, until it comes to a rest.

It is possible to impulse a pendulum using electromagnets, but the energy has to come from someplace.
