Identify the increasing order of the angular velocities of the following: (I) Earth rotating about its own axis (II) hour's hand of a clock (III) second's hand of a clock
Correct answer: A. I,II, III
- A. I,II, III
- B. III, I, III
- C. ll, lll, I
- D. III, II, I
Explanation
Earth completes one rotation in 24 hours Hour hand completes one rotation in 12 hours Second hand completes one rotation in 1 minute ωEarth < ωHour < ωSecond

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.
