# Moment of inertia of a Point mass

`I = m*r^2`

I is the mass moment of inertia of a particle (point mass).**Enter 'x' in the field to be calculated.**

The mass moment of inertia of a point mass at a distance r from axis of rotation is calculated as follows,

`I = m * r^2`

m : mass of the particle in kilogram (kg)

r : distance between the point and the axis of rotation in meter (m)
