"The seconds pendulum (also called the Royal pendulum), 0.994 m (39.1 in) long, in which each swing takes one second, became widely used in quality clocks. The long narrow clocks built around these pendulums, first made by William Clement around 1680, became known as grandfather clocks . See more A seconds pendulum is a pendulum whose period is precisely two seconds; one second for a swing in one direction and one second for the return swing, a frequency of 0.5 Hz. See more A pendulum is a weight suspended from a pivot so that it can swing freely. When a pendulum is displaced sideways from its resting equilibrium position, it is subject to a restoring force due to gravity that will accelerate it back toward the equilibrium position. When … See more The length of a seconds pendulum was determined (in toises) by Marin Mersenne in 1644. In 1660, the Royal Society proposed that it be the standard unit of length. In 1671 Jean Picard measured this length at the Paris observatory. He found the value of 440.5 See more The pendulum clock was invented in 1656 by Dutch scientist and inventor Christiaan Huygens, and patented the following year.

WebThis section introduces an old definition of 'meter' which uses a seconds pendulum. A 'meter' is the length of a seconds pendulum, which swings a full cycle in 2 seconds in small angles. The French National Assembly also accepted another definition of 'meter' to be "the length of a pendulum with a half-period of one second" in year 1790.
