Introduction:A simple pendulum has a small-diameter bob and a string that has an exceedingly small mass butis strong enough not to stretch appreciably and is suspended from a light wire or string. The lineardisplacement from equilibrium is s, the length of the arc. It is a resonant system (a naturalfrequency of vibration determined by the physical parameters of the vibrating object) with a singleresonant frequency. For small amplitudes, the period of such a pendulum can be approximated by:𝑇 = 2𝜋√𝐿/𝑔(HyperPhysics, 2010). Pendulums are in common usage. Some have crucial uses,such as in clocks; some are for fun, such as a child’s swing; and some are just there, such as thesinker on a fishing line. The vertical distance between the point of suspension and the centre ofmass of the suspended body (when it is in mean position) is called the length of the simplependulum denoted by L (Main, 2021). Laws of Simple Pendulum are 1. Law of mass: The timeperiod is independent of the mass of the bob. 2. Law of length: The time period is directlyproportional to the square root of the length.3. Law of Iscochronism: The time period isindependent of the amplitude as long as the amplitude is small. 4. Law of gravity: The time periodis inversely proportional to the square root of the acceleration due to gravity at that place (Bhuyan,2020). The restoring force of the physical pendulum is the force of gravity. With the simplependulum, the force of gravity actually acts on the centre of the pendulum bob and provides therestoring force that causes the object to oscillate. The forces of gravity, the mass of the pendulum,
