In which case application of angular velocity is useful?
Correct answer: A. When body is rotating.
- A. When body is rotating.
- B. When velocity of body is in a straight line.
- C. When velocity is in a straight line.
- D. None
Explanation
Angular velocity is particularly useful when dealing with rotational motion. It describes how fast an object rotates 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.
