(i) The angular momentum of a particle with respect to a point gives an idea of the strength of its rotational tendency about that point.

(ii) The magnitude of the angular momentum is defined in terms of mass and velocity of the particle and its distance from the reference point, i.e.,

L = mvr

(iii) The vector concept of the angular momentum is useful. Its direction is the axial direction given by

right hand rule
