# What is the formula for Moment of Inertia of a particle?

Posted in ROTATIONAL MOTION | Email This Post |Moment of inertia of a particle about an axis is equal to the product of the mass of the particle and square of its distance from the axis.

The formula for Moment of Inertia of a particle is given as,

Moment of inertia of the particle about the axis = mass of the particle (m) × distance of particle (r)

from the fixed axis

Formula for Moment of inertia of the particle about the axis = mr^{2}

The S.I. unit for moment of inertia is kg m^{2}
