19. Periodic action
A vibration is a constant series of energy bursts. We can also put gaps between those energy bursts to create Periodic action. If you are using continuous force, pulsed energy can be more effective (this is what a hammer drill does). You can change the force, how long it is applied and how long between each application. Rear cycle lamps were once all constantly red, then someone came up with the idea of a flashing light which not only saves energy, it also attracts motorists' attention.
