A pendulum is a device made of a weight suspended from a pivot so that it can swing freely. [1] 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.
Aug 5, 2024 · The Dutch mathematician and scientist Christiaan Huygens invented a clock controlled by the motion of a pendulum in 1656.

- A pendulum is a body suspended from a fixed point so that it can swing back and forth under the influence of gravity. The time interval of a pendul...
- Different types of pendulums have different applications. Examples of simple pendulums are found in clocks, swing sets, and even the natural mechan...
- Pendulum clocks are powered by mechanisms that trigger the pendulum to swing with a constant period. Traditionally, weight or spring mechanisms ful...
- Some authorities ascribe the invention of the pendulum clock to Galileo, while others credit Christiaan Huygens. This disagreement arises because G...
Apr 24, 2017 · In 1818, Henry Kater devised the reversible Kater's pendulum to measure gravity, and it became the standard measurement for gravitational acceleration over the next century.
Galileo's first notes on the subject date from 1588, but he did not begin serious investigations until 1602. Galileo's discovery was that the period of swing of a pendulum is independent of its amplitude--the arc of the swing--the isochronism of the pendulum.
He became the first to report the phenomenon of coupled oscillation in two pendulum clocks (which he invented) in his bedroom while recovering from an illness in 1665. Huygens was born in 1629 in The Hague, Netherlands, to a wealthy and influential family; his father, Constantijn, was a diplomat with many useful connections in government ...
At one time the Kenyon College physics department had a master clock with a pendulum that sent out electrical time signals to many of the rooms used by physics. The 1928 catalogue of Max Kohl of Chemnitz, Germany identifies this apparatus as Overbeck's Cross Pendulum.
A simple pendulum is a mass, suspended from a point, that is free to swing under the force of gravity. It's motion is periodic and the math is almost simple. chaos
