Question

what is angular momentum perpendicular​

Answer 1

Explanation:

The direction of angular velocity and angular momentum are perpendicular to the plane of rotation. Using the right hand rule, the direction of both angular velocity and angular momentum is defined as the direction in which the thumb of your right hand points when you curl your fingers in the direction of rotation.

Answer 2

Answer:

Angular momentum is a vector, so it must have a direction assigned to it. (Even though it might not seem as logical as the direction of a vector in linear motion). The only option remaining for consideration then, for the direction of the momentum vector, is a direction perpendicular to the plane of rotation
