SOLAR SYSTEM

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: -Purely rotational motion occurs if every particle in the body moves in a circle about a single line. This line is called the axis of rotation. Then the radius vectors from the axis to all particles undergo the same angular displacement at the same time. The axis of rotation need not go through the body.

Detailed explanation-3: -“Rotational motion can be defined as the motion of an object around a circular path, in a fixed orbit.” The dynamics for rotational motion are completely analogous to linear or translational dynamics.
