Angular Momentum Calculator for Rotational Object

Use our angular momentum calculator, a free online tool to calculate the angular momentum of a rotating object for the given inertia and velocity.

If the angular velocity of the object is ω and its moment of inertia about the given axis is I, then its angular momentum about the axis is

Angular Momentum (L) = Moment of Inertia (I) x Angular Velocity (ω)

L = Iω

Angular Momentum

What is angular momentum?

Angular momentum is the quantity of rotation of a body, which is the product of its moment of inertia and its angular velocity.

Unit of Angular Momentum

The SI unit of angular momentum is kilogram meter square per second (Kg m2/s). Angular momentum is a vector quantity, meaning it has a magnitude and a direction. The vector points in the same direction as the ω (that is in the direction of the thumb of your right hand points when you wrap your fingers around in the direction the object is turning).
