Here's a breakdown:

* M: Mass (kg)

* L: Length (m)

* T: Time (s)

Derivation:

Angular momentum (L) is defined as:

L = Iω

Where:

* I: Moment of inertia ([M L²])

* ω: Angular velocity ([T⁻¹])

Therefore, the dimension of angular momentum is:

[L] = [I] * [ω] = [M L²] * [T⁻¹] = [M L² T⁻¹]

Units of Angular Momentum:

The standard unit of angular momentum is the kilogram meter squared per second (kg m²/s).
