The swinging motion of the pendulum is transmitted to a system of gears and levers, which turn the hands of the clock to display the time.
In mechanical clocks, this is often achieved using a pendulum, which swings back and forth at a fixed rate. An oscillator is a device that produces regular, repeating vibrations at a constant frequency.
The exact workings of a clock depend on its type and design, but most clocks use some form of oscillator to regulate their timing. The word "clock" enters the language around the 14th century, around the time when clocks started hitting the mainstream.Ĭlocks have played an important role in human history, helping to regulate work schedules, coordinate transportation, and synchronize scientific experiments.Ī clock works by using a system of mechanisms to measure the passage of time and display it in a useful and accurate way.
