Angular momentum is a fundamental concept in physics that describes the rotational motion of an object. It is a vector quantity defined as the product of an object's moment of inertia and its angular velocity. Mathematically, angular momentum (L) can be expressed as:
L = Iω
Where:
- L is the angular momentum,
- I is the moment of inertia, and
- ω is the angular velocity.
The radius of gyration is the distance from an axis of a body to the point in the body whose moment of inertia is equal to the moment of inertia of the entire body. The radius of gyration is equal to the square root of the ratio between the moment of inertia of the entire body and the mass of the whole system.
