I just thought of this, will it work?

[Low-Q]

If the pendulum weight shifts position all the time, the pendulum will stop sooner. If you consider the rod as weightless, the weight will not change or turn around by itself. Consider that the weight is in free fall all the time. Not before you manually stop the pendulum in one of the outer positions, the weight will flip over - because you stop the free fall. As soon as the weight then are flipping over and now are closer to the ground, its potential energy is reduced, and the pendulum loose its kinetic energy.


It will not work.
