Kilogram Square Meter

kg·m²

Definition

The kilogram square meter (kg·m²) is the SI unit of moment of inertia, representing the resistance of a body to angular acceleration. It is calculated as the sum of the products of mass and the square of the distance from the axis of rotation.

History/Origin

Derived from the SI base units of mass (kilogram) and length (meter). It became the standard unit for moment of inertia in the International System of Units, fundamental in rotational dynamics and mechanical engineering.

Current Use

Widely used in mechanical engineering, physics, and robotics to calculate rotational motion, design rotating machinery, analyze gyroscopic effects, and solve problems involving angular momentum and torque.
