Question

What is Moment of inertia ?What is moment of inertia of circular disc?​

Answer 1

Moment of inertia about a given axis of rotation resists a change in its rotational motion; it can be regarded as a measure of rotational inertia of the body. It is a measure of the way in which different parts of the body are distributed at different distances from the axis.

Moment of inertia of circular disc is mr^2

Answer 2

Explanation:

Moment of inertia of a circular disc about an axis through its center of mass and perpendicular to the disc: Icm=MR22, where Icm is the moment of inertia about center of mass, M is the mass of the uniform circular disc and R is the radius of the uniform circular disc.
