Question

define moment of inertia of a rigid body .also give its si units​

Answer 1

Answer:

a quantity expressing a body's tendency to resist angular acceleration, which is the sum of the products of the mass of each particle in the body with the square of its distance from the axis of rotation

Explanation:

SI unit is kg m^2

Answer 2

moment of inertia = the moment of inertia of a rigid body about a given axis is defined as the sum of the products of the mass of each and every particle of the body and the square of it's distance from the given axis S.i. Unit of mount of inertia is kg msquare and c.g.s system it is g cm square
