What is a pendulum and how does it work?
Pendulum clocks have been around since the 17th century. This type of clock has a pendulum and works via weights, though in modern examples, it may be a spring winder. Weights are what keep the clock running and ensure it keeps accurate time. The pendulum clock was the first accurate clock.FeaturesThe pendulum clock consists of a face divided into hours, minutes and seconds. Traditional pendulum clocks have one or more weights. The pendulum, which is a weight on the end of a rod, is the part that gives the clock its name. Pendulum clocks can be free standing (as with the grandfather clock) or hung on the wall (as with a cuckoo clock). Every second on a wall clock, the pendulum swings; but on a grandfather clock, which is much larger, the pendulum swings every two seconds.WeightsThe weights on a pendulum clock are designed to hold energy that makes the clock run for extended periods. When a pendulum clock is wound up, it activates a cord that pulls on the weight. Because of gravity, thi
