This image is a composite of ten photos shot at four frames per second by a tripod-mounted remote-activated camera at a lake near my cabin in Wisconsin. The image shows the photographer riding a rope swing from its maximum displacement on the right to the left. In this way, the photographer and the rope swing demonstrate part of the period of a simple pendulum. In simple pendulums, a mass is suspended by some length of material from a pivot point, is displaced, and is allowed to swing freely. In this case, the mass is the photographer (myself), the material is rope, and the pivot point was a tree branch of questionable stability.
