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. Heavily damped
Explanation
In undamped oscillations, the amplitude remains constant over time. The absence of dissipative forces, such as friction or air resistance, allows the oscillating system to conserve its energy, leading to sustained oscillations with a constant amplitude. Unlike damped oscillations, where energy is gradually lost to external forces, undamped oscillations exhibit a persistent and unchanging amplitude throughout the oscillatory motion.

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.
