When a car moves on any uneven surface, then its shock absorbers play an important role. The working of shock absorbers exemplifies
Correct answer: C. Damped oscillation.
- A. Free oscillation.
- B. Forced oscillation.
- C. Damped oscillation.
- D. Undamped oscillation.
Explanation
The correct answer is damped oscillation. Shock absorbers are designed to reduce the amplitude of vibrations caused by uneven surfaces by dissipating energy, which is a characteristic of damped oscillation. Free oscillation does not involve external forces or damping, forced oscillation requires continuous external driving forces, and undamped oscillation does not account for energy loss, making these options incorrect for describing the function of shock absorbers.

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.
