Circular motion is a fundamental concept in physics that involves an object moving along the circumference of a circle or rotating along a circular path. This motion can either be uniform, with a constant angular rate of rotation and speed, or nonuniform, with a changing rate of rotation. When a three-dimensional body rotates around a fixed axis, its parts undergo circular motion. The equations of motion are used to describe the movement of the body’s center of mass.This book presents a deeper understanding of the dynamics and forces at play in a wide range of natural and engineered systems. This knowledge has numerous practical applications in fields such as astrophysics, engineering, and transportation, enabling us to comprehend and manipulate the complex motions of objects moving along curved paths.
