Rotational inertia of a body is defined as
for a system of discrete particles (each of mass mi), and as
for a body with continuously distributed mass (dm is the mass element). ri and r represent the perpendicular distance from the axis of rotation to the mass element of the body.
SI unit for rotational inertia is kg m2.
