# Rotation

- Angular Momentum - Angular momentum is a physical quantity that represents the rotational inertia of an object combined with its rotation speed. This calculator computes angular momentum given moment of inertia and angular velocity.
- Conservation of Angular Momentum - The conservation of angular momentum states that the total angular momentum of a system remains constant if no external torques act on it.
- Moment of Force - The moment of a force produces rotation and is defined as the product of the force and the perpendicular distance from the point to the line of action of the force.
- Torque - The torque is calculated by multiplying the applied force with the lever arm distance. This calculator helps find the torque.
