Origin of 'pendulum'

Main points about word origin

  • The word comes from the Latin 'pendulus', meaning 'hanging'.
  • In the 17th century, scientists began using the term to describe the swinging device used in clocks.
  • Pendulums have been used in various languages, highlighting their significance in timekeeping across cultures.

The word 'pendulum' originated from the Latin word 'pendulus', which means hanging. The concept of a swinging weight to regulate time dates back to ancient civilizations, such as the use of water clocks and sundials. The modern pendulum clock was invented by Dutch scientist Christiaan Huygens in the 17th century. Since then, the pendulum has been widely used in various applications, from timekeeping devices to scientific experiments.
