SUMMARY
This discussion clarifies the application of vectors in the context of rotation, specifically using the right-hand rule to determine angular velocity and angular momentum. The right-hand rule indicates that for clockwise rotation, the angular vector points downward, while for counter-clockwise rotation, it points upward. It is emphasized that rotation itself does not possess vectors; rather, vectors such as angular velocity describe the rotational motion. The instantaneous velocity of a point on a rotating object, like a vinyl record, is tangential to its circular path, not in the direction of the angular vector.
