Answer: A pendulum is a weight that is suspended from a pivot and can freely swing. Its period is the amount of time it takes to complete one full cycle, which includes both a left and right swing.
According to the laws of simple pendulum.
A simple pendulum’s period is directly proportional to the square root of its length.
A simple pendulum’s period is inversely related to the square root of gravity’s acceleration.
A simple pendulum’s period is independent of its mass.
A simple pendulum’s period is independent of its amplitude.
