## About Rotational Momentum Calculator (Formula)

Rotational momentum, also known as angular momentum, is a measure of the amount of rotational motion an object has. The rotational momentum of an object depends on both its mass and the speed at which it is rotating.

The formula for rotational momentum is given by:

**p = I * Va**

where: p is the rotational momentum (kg * m^2/s) I is the momentum of inertia (kg * m^2) Va is the angular velocity (rad/s)

The momentum of inertia is a measure of an object’s resistance to rotational motion, and it depends on the distribution of mass in the object. The angular velocity is the rate at which an object is rotating, measured in radians per second.

It’s important to note that rotational momentum is a vector quantity, meaning it has both magnitude and direction. The direction of rotational momentum is perpendicular to the plane of rotation, and its magnitude is proportional to the object’s speed of rotation.
