The angular velocity of a body moving along a circular path can be manipulated as a scalar if:
Correct answer: B. Axis of rotation is fixed
- A. Angular speed is slow
- B. Axis of rotation is fixed
- C. Mass of body is very light
- D. Both "A" and "B"
Explanation
When axis of rotation is fixed then all angular vectors have the same direction. Hence they can be manipulated as scalars.

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.
