![]() Every mechanical clock needs energy to run. This is why all mechanical clocks must be wound to continuously keep accurate time. Instead, they harness the energy stored in a wound spring. ![]() Unlike their digital and quartz counterparts, mechanical clocks don’t depend on a battery to keep time. How do old clocks work without batteries? Inertia causes the pendulum to stay at rest unless a force causes it to move. When the pendulum is hanging still, the wire and weight are straight and at a 90-degree angle to the Earth as gravity pulls the string and the weight to the Earth. ![]() The Earth’s gravity attracts the pendulum. In the event that it still doesn’t run, try carefully and fully winding the weights. Afterward, set the pendulum so it swings again. Set it back by half an hour, then immediately move it forward to the hour and allow for it to cuckoo. If your cuckoo clock still doesn’t run, then it’s time to move the minute hand. Why won’t the pendulum keep swinging on my cuckoo clock? The truth is, some mechanical clocks cannot be set backwards, but most actually can! So why is this such a common misconception? Many of the American clocks made around the turn of the century were the kind that you can’t turn backwards. Only in a theoretical situation when there is no friction the pendulum will oscillate forever. The pendulum loses energy because of friction. The pendulum stops eventually because of air resistance. What force stops a pendulum from swinging? A pendulum is an object hung from a fixed point that swings back and forth under the action of gravity. Other factors, including a pendulum’s length, can also affect its motion. This is because the swinging motion of a pendulum is due to the force of gravity generated by the earth’s size. This means that there is a relationship between the gravitational field (g) and Pi. A pendulum with a length of 1 meter has a period of about 2 seconds (so it takes about 1 second to swing across an arc). How long does it take a pendulum to swing? Open the front door and hang the pendulum on the hook (on many clocks the hook is behind the dial), give the pendulum a swing, and the clock will start ticking. Place the clock where it is to be used, on a stable, level surface. Little did I know back then, but pendulum clocks don’t need batteries at all! And the pendulum itself? It may seem like it’s just idling around, serving no real purpose as it swings to and fro, but that action is actually what keeps the clock accurate to the second. This only takes a few minutes to readjust and all pendulum clock owners should learn how as this will happen eventually. Often a pendulum clock will stop when it has been moved, bumped or even a too aggressive push to restart a pendulum. Even without air friction, the friction which exists with the point around which the pendulum rotates causes the system to lose kinetic energy and eventually stop. What force makes a pendulum stop swinging? A pendulum stops oscillating because it loses energy when it is converted into heat. What causes a pendulum to eventually slow down and stop swinging? How does a pendulum work on a battery clock? Don’t worry about making your clock absolutely level with the floor and don’t use a level. The reason a clock pendulum often stops swinging, after being moved, is because the clock case now leans at a slightly different angle then it did at its former location.
