A pendulum is one of the simplest and most elegant systems used to understand how motion works. It consists of a mass suspended from a fixed point so it can swing freely under the influence of gravity. When displaced from its resting position and released, it moves back and forth in a smooth, periodic arc. This motion is governed by the balance between gravitational pull and momentum, creating a rhythm that stays remarkably consistent for small swings. Because of this predictability, pendulums h
