Variation of amplitude with respect to time for an oscillation object is shown in figure. Identify the oscillation:
Correct answer: C. Undamped
- A. Damped
- B. Critical
- C. Undamped
- D. Non-critical
Explanation
There is no change in the oscillation's amplitude hence it is undamped.

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.
