Question

Which of the following are correct units for angular momentum?

A) kgm/s

B) kgm^2/s^2

C) kgm^2/s

D) kgrad/s

E) kgrad/s^2

Answer 1

The correct units for angular momentum are kgm^2/s (option C) and kgm^2/s^2 (option B).

Step-by-step explanation:

The correct units for angular momentum are kgm^2/s (option C) and kgm^2/s^2 (option B).

Angular momentum is a vector quantity that represents the rotational motion of an object. It depends on the mass, velocity, and distribution of mass in an object.

In option C, the unit kgm^2/s represents the product of the mass (kg), the square of the distance from the axis of rotation (m^2), and the velocity (s^-1).

In option B, the unit kgm^2/s^2 represents the product of the mass (kg), the square of the distance from the axis of rotation (m^2), and the square of the velocity (s^-2).
