Angular Momentum-FAQs
1. What is Angular Momentum?
Angular momentum is defined as the product of Moment of Inertia and Angular Velocity of any Rotating Object.
2. What is Principle of Conservation of Angular Momentum?
According to the Law of Conservation of Angular momentum, when no external torque acting on the system, the angular momentum of the object is always conserved.
3. Is Angular Momentum is Scalar or Vector Quantity?
Angular Momentum has both magnitude and direction, therefore it is a Vector Quantity.
4. What is Angular Momentum Quantum Number?
Azimuthal quantum number or secondary quantum number is interchangeable with angular momentum quantum number. It is a quantum number that determines the angular momentum of an atomic orbital as well as its size and form. The most common value is between 0 and 1.
5. What is Angular Momentum and Moment of Inertia?
Angular Momentum of any object is the product of the Moment of Inertia and the Angualr Velocity of an object. Whereas, Moment of Inertia (MOI) is the measure of how the mass of object is distributed about the axis of rotation.
6. Is Angular Momentum Always Conserved?
No, Angular momentum is conserved only when no net external torque is applied to rotating body.
Angular Momentum
Angular Momentum is a kinematic characteristic of a system with one or more point masses. Angular momentum is sometimes called Rotational Momentum or Moment of Momentum, which is the rotational equivalent of linear momentum. It is an important physical quantity as it is conserved for a closed system and follows the Law of Conservation of Angular Momentum. Angular Momentum is equal to the product of the moment of inertia (I), and the angular velocity (ω), of an object in rotational motion. Angular Momentum is a vector quantity. The SI unit of angular momentum is Kg.m2.s-1
