Escapement and the clock
A pendulum regulates an ideal anchor escapement. Event-based impulses replace dissipated energy, while measured tick intervals reveal the dependence on length and amplitude.
Try this
Wind the clock, change losses and watch the anchor deliver impulses. Click the bob to nudge it.
Equations used in the module
