Explained in Ridiculously Simple Words. $11.27. By using the correct amount of mercury, the centre of gravity of the pendulum remained at a constant height, and thus its period remained constant, despite changes in temperature. It was made by Clemens Riefler in Germany. Eventually the clock will stop running from this resistance. These are some of the different styles of pendulum clocks: Vienna regulator style pendulum wall clock. Artwork: A pendulum is constantly swapping potential energy and kinetic energy. Photo by Anders Sandberg published on, Photo: One of the most accurate pendulum clocks ever made Fine adjustment of the rate of the clock could be made by slight changes to the internal pressure in the sealed housing. Galileo discovered the key property that makes pendulums useful timekeepers: isochronism, which means that the period of swing of a pendulum is approximately the same for different sized swings. $104.99. During the Industrial Revolution, the faster pace of life and scheduling of shifts and public transportation like trains depended on the more accurate timekeeping made possible by the pendulum. If you were to substitute a pendulum from an old mechanical movement, you would probably find that the pendulum is to heavy to be operated by a battery operated movement. explainthatstuff.com, The Feynman Lectures on Physics, boxed set: The New Millennium Edition, QED: The Strange Theory of Light and Matter (Princeton Science Library, 90).
