Detailed explanation-1: -Rotation describes the circular motion of an object around its center. There are different ways things can rotate. A very familiar kind of rotation is when a spherical, three-dimensional object turns around an invisible line inside its center. This center is called an axis .
Detailed explanation-2: -These rotations are called precession, nutation, and intrinsic rotation.
Detailed explanation-3: -The two fundamental concepts which are studied in circular motion are rotation and revolution. While rotation means the movement in a circle round an axis, revolution is when an object moves in a circular path around another object or center.
