Question

Angular velocity and angular acceleration are not vectors why

Answer 1

The magnitude, or length, of theangular acceleration vector is directly proportional to the rate ofchange of angular velocity, and is measured in radian s per second squared (rad/s 2 or rad. s -2 ). ... The angular acceleration vectordoes not necessarily point in the same direction as the angular velocity vector.

Answer 2

although angular velocity and angular acceleration are not vectors they come under pseudovectors .
they are not known as vectors coz they do not react during the presence of light.
