simple pendulum

A simple pendulum is an idealized device consisting of a point mass suspended by a massless, inextensible thread, free to swing without friction under the influence of gravity. Its defining characteristic is that the time for each complete back-and-forth swing, known as the period, remains constant. This property, first observed by Galileo, led to the development of accurate mechanical clocks. The period of a simple pendulum is determined by its length and the acceleration due to gravity, but it is independent of the mass of the suspended object.1234
