Question

State the S.I. unit of angular momentum. Obtain its dimensions.

Answer 1

Hint: Angular momentum, a typical function of a rotary inertia in a topic or network of objects in motion, on an axis on which the object or structure may or does not move. Owing to the periodic movement around the Planet and the regular rotation around the Planet, the earth has orbital angular dynamics.

Step-by-step answer:
Angular momentum is a quantity of the line, which involves a definition of the scale and the path. The scale of the angular momentum of a moving object equals its linear momentum (product of its mass m and linear speed v) to the perpendicular distance r from the center of rotation to a line that moves along or literally mvr or its center of gravity. The cumulative angled momentum is a persistent reality for a single body or device separated from external influences, a reality regarded as the law of retaining angular momentum. For example, a rigid rotating body continues to move at a constant pace and with a set direction, even when the external torque is applied.
The appropriate MKS and SI units are kilograms per second ($kg{m^2}/\sec $) squared for angular momentum.
Dimensional formula-
$ \Rightarrow {M^1}{L^2}{T^{ - 1}}$
Where, M is mass, L is the length, and T is time.

Note: The angular momentum will on the other hand be assumed for a moving body to be a summation of the volume of mvr over all the particles that form it. Corner momentum may be defined in the same manner as I, the moment of friction, and è l, the angular direction, a spinning object or mechanism. The orientation of the angular vector is that of the spinning axis of the given body and the position of a right-hand torch will travel if turned likewise is marked as positive.
