ANGULAR MOMENTUM Meaning and
Definition
-
Angular momentum is a fundamental concept in physics that describes the rotational motion of an object or a system of objects. It refers to the measure of the amount of rotational motion possessed by an object or a collection of objects rotating around a fixed axis.
Angular momentum is defined as the product of the moment of inertia and the angular velocity. The moment of inertia represents the resistance of an object to changes in its rotational motion and depends on its mass distribution and shape. The angular velocity is the rate at which an object rotates around an axis.
Mathematically, angular momentum (L) is calculated as L = Iω, where I is the moment of inertia and ω is the angular velocity. The unit of angular momentum is kilogram meters squared per second (kg·m²/s), equivalent to joule-seconds (J·s).
Angular momentum is a conserved quantity, meaning that its total value remains constant in an isolated system in the absence of external torques. This conservation principle finds applications in various physical phenomena, such as the motion of planets around the Sun, spinning objects like gyroscopes, and the stability of rotating systems.
In summary, angular momentum quantifies the rotational motion of an object or a system, combining the effects of its mass distribution and rotational speed. It plays a crucial role in analyzing and understanding rotational dynamics and is conserved in the absence of external torques.

Etymology of ANGULAR MOMENTUM
The word "angular momentum" is formed by combining two separate words: "angular" and "momentum".
1. Angular: The word "angular" comes from the Latin word "angulus", which means "corner" or "angle". It has its roots in the Proto-Indo-European word "ank-", meaning "to bend". Over time, "angular" came to describe things related to angles or having an angular shape.
2. Momentum: The word "momentum" also originates from Latin, derived from the words "momentum" or "momenta", which means "movement" or "motion". It was originally used in the context of physics to denote the quantity of motion of a moving object.
By combining these two words, "angular" and "momentum", the term "angular momentum" refers to the rotational counterpart of linear momentum in physics.
