England Swings Like A Pendulum Do

A pendulum endlessly interconverts potential (a) and kinetic energy (v)--at the high point of each upswing, the weight is motionless as it reverses course-at that moment all its energy is potential, given by the weight. As the weight swings downward in an arc, that potential converts to pure kinetic energy as it swings through the midpoint.  Back and forth it goes, slowed only by friction in air or of the pivot point.

Soothing harmonics blogged to make a point later.
