SUMMARY
Angular momentum is defined using the cross product of the position vector (r) and the momentum vector (p), expressed as r x p. This mathematical operation is essential because it accounts for the perpendicular direction of angular momentum, which is not captured by the dot product (r . p). The cross product inherently incorporates the directional aspect of rotational motion, making it the appropriate choice for calculating angular momentum.
