Definition:Angular Momentum of Particle/Also presented as

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.
