Definition
Some sources present the definition of the angular momentum of a particle $P$ relative to a point $A$ as:
- $\mathbf L = \paren {\mathbf r - \mathbf r_A} \times m \mathbf v$
where:
- $m$ denotes the mass of $P$
- $\mathbf v$ velocity of $P$ relative to the frame of reference in which the motion of $P$ is defined
- $\mathbf r$ denotes the position vector of $P$
- $\mathbf r_A$ denotes the position vector of $A$
- $\times$ denotes the vector cross product.
Also known as
Angular momentum is also (rarely) known as moment of momentum or rotational momentum.
