The direction of angular velocity is along:
Correct answer: B. Axis of rotation
- A. Along the tangent of circular path
- B. Axis of rotation
- C. Inward the radius
- D. Outward the radius
Explanation
Angular velocity is a cross product using the right hand rule for direction. If you think about it, the vector being along the axis of rotation uniquely defines the direction in which the object is rotating.

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.
