What is angular velocity?
Correct answer: A. Change in angular rotation / change in time
- A. Change in angular rotation / change in time
- B. Change in displacement / change in time
- C. Change in speed / change in time
- D. Change in acceleration / change in time
Explanation
Angular velocity is the time rate at which an object rotates or revolves about an axis. Angular velocity is represented by the Greek letter omega (ω, sometimes Ω). It is measured in angle per unit time; hence, the SI unit of angular velocity is radians per second. Also;Angular velocity is the vector measure of the rotation rate, which refers to how fast an object rotates or revolves relative to another point. In simple words, angular velocity is the time rate at which an object rotates or revolves about an axis.

About Angular Velocity
Angular velocity describes how quickly angular displacement changes with time, with ω = Δθ/Δt and units of radians per second. Questions relate angular and linear motion through v = rω, use the direction given by the right hand rule, and distinguish angular velocity from angular acceleration and ordinary frequency.
