Question

Define moment of inertia.

Answer 1

Moment of Inertia (I) is the measure of an object's resistance to changes in its rotational motion about a given axis. It is defined as the sum of the products of the masses of the individual particles of the body and the square of their perpendicular distances from the axis of rotation. Mathematically, it is expressed as:

`I = summ_ir2/i`
