A body moves with constant angular velocity in a circle. Magnitude of angular acceleration is:
Correct answer: C. Zero
- A. rω2
- B. Constant
- C. Zero
- D. rω
Explanation
If an object is moving in a circle with constant angular velocity, the magnitude of the angular acceleration is zero. This is because angular acceleration is the rate of change of angular velocity, and if the angular velocity is constant, there is no change occurring, leading to zero angular acceleration.

About Simple Harmonic Motion
Simple harmonic motion is oscillation in which acceleration is directly proportional to displacement and directed toward the equilibrium position. Work includes displacement, velocity, acceleration, phase, period, frequency, amplitude and energy, with applications to springs and simple pendulums. The restoring force and the conditions for SHM distinguish it from general periodic motion.
