Moment of inertia: The moment of inertia of a body about a given axis of rotation is defined as the sum of the products of the masses of the particles of the body and the squares of their respective distances from the axis of rotation.
DIMENSIONS: [M¹L²T⁰]
SI UNIT: kilogram meter² (kgm²)
The moment of inertia of a rigid body depends on : (i) the mass and shape of the body (ii) orientation and position of the rotation axis (iii) distribution of the mass about the rotation axis.
