If a rock is attached to a massless, rigid rod and swung in avertical circle at constant speed, it will not have a constanttotal energy. The kinetic energy will be constant, but thepotential energy will be continually changing. Is any workbeing done on the rock? Does the rod exert a tangential forceon the rock?
