# Angular Momentum Calculator

Angular momentum is the rotational equivalent of linear momentum. The moment of inertia is a tensor which provides the torque needed to produce a desired angular acceleration for a rigid body on a rotational axis otherwise. This online angular momentum calculator helps you in finding angular momentum of an object and the moment of inertia. In this online moment of inertia calculator enter the mass of the object, angular speed, the radius of orbit and submit to get the results.

Angular momentum is the rotational equivalent of linear momentum. The moment of inertia is a tensor which provides the torque needed to produce a desired angular acceleration for a rigid body on a rotational axis otherwise.

#### Formula:

Moment of Inertia = Mass x Radius2 / 2 Angular Momentum = Moment of Inertia x Angular Speed

### Example:

Calculate angular momentum from moment of inertia of a rod of radius 10 m and mass 50 kg which is rotating with the angular speed of 20 ms-1.

#### Solution:

Moment of Inertia = Mass x Radius2 / 2
= 50 x 102 / 2
= 2500 kgm2

Angular Momentum = Moment of Inertia x Angular Speed
= 2500 x 20
= 50000 kgm2s-1
