Angular KinematicsMediumQuestion 6124

Question

A particle moves in circle. Its angular acceleration is zero. This means:
  1. A
    It is at rest
  2. B
    Angular velocity is zero
  3. C
    Angular velocity is constant
    Correct
  4. D
    Radius changes

Correct answer

Angular velocity is constant

Explanation

α = dω/dt = 0 means ω = constant (uniform circular motion).
