(1/4)MR²
(1/4)एमआर²

(2/5)MR²
(2/5)एमआर²

For a solid cylinder of mass $M$ and radius $R$ rotating about its central axis, the moment of inertia is:

I = \frac{1}{2}MR^2

This quantifies how mass is distributed relative to the axis of rotation, affecting the object's resistance to angular acceleration.
