Question

(a) Define angular velocity? And write its SI unit.

Answer 1

Answer:

angular velocity refers to how fast an object rotates or revolves relative to another point, i.e. how fast the angular position or orientation of an object changes with time. There are two types of angular velocity: orbital angular velocity and spin angular velocity.

In SI base units: s−1

Explanation:

Answer 2

Answer:

The angular velocity specifies the angular speed at which an object is rotating along with the direction in which it is rotating. It is a vector quantity. The SI unit of angular velocity is radians per second. ... Angular velocity is usually represented by the symbol omega (Ω or ω).
