According to this theorem, the moment of inertia I of a body about any axis is equal to its moment of inertia about a parallel axis through centre of mass, Icm, plus Ma2 where M is the mass of the body and V is the perpendicular distance between the axes, i.e., • If no external force acts on the body, then the centre of mass will have constant momentum. A rigid body performs a pure rotational motion, if each particle of the body moves in a circle, and the centre of all the circles lie on a straight line called the axes of rotation. The circular paths of all the point masses have a common centre. • Radius of Gyration • Theorem of Perpendicular Axes • Theorem of Parallel Axes The combination of rotational motion and the translational motion of a rigid body is known as rolling motion.
