Question

Angular momentum is:
A. A scalar
B. A polar vector
C. An axial vector
D. Not a physical quantity

Answer 1

Hint: To know what type of physical quantity angular momentum is we have to see what is meant by angular momentum:
Angular momentum is a calculation of the body’s momentum in rotational motion. The angular momentum of rigid bodies is maintained, thus the rotating sphere will continue to rotate until the external force acts. The change in angular momentum is equivalent to a torque.

Complete step by step answer:
Now let us see about angular momentum in brief:
Angular momentum of the system is retained as long as there is no net external torque operating on the system; the planet rotates on its axis from the time the solar system was created due to the law of accumulation of angular momentum.
There are two ways to measure the angular momentum of some object, if it is a point object in a rotation, then our angular momentum is proportional to the radius times the linear momentum of the object.
If we have an extended object, the angular momentum is given by the moment of inertia, i.e. how much mass is in motion in the object, and how far it is from the centre, times the angular velocity.
Angular momentum is the pace of change of angular displacement and is vector amount (all the more definitely, an axial vector) which determines the precise speed (rotational speed) of an item and the axis about which the object is turning and axial vector is an amount that changes like a vector under a good revolution.
From the above discussion we have observed that angular momentum is an axial vector.

Hence, option C is correct.

Note: We may get confused between axial vector and polar vector, but since angular momentum is associated with rotational motion about the axis. So, it is an axial vector.
