In desert Safari, drivers use best quality of shock absorbers in their cars to createI.free oscillationII.forced OscillationIII.damed oscillation
Correct answer: B. III only.
- A. I only.
- B. III only.
- C. I and II.
- D. II and III.
Explanation
The correct answer is III only. Shock absorbers are designed to create damped oscillation. This type of oscillation helps to reduce the amplitude of vibrations and bring the vehicle back to equilibrium smoothly after encountering bumps or rough terrains, which is essential for a comfortable ride during a desert safari. Free oscillation is not applicable here as it involves oscillations that occur without external forces. Forced oscillation involves continuous external forces, but the primary goal of shock absorbers is to dampen and control these forces rather than sustain them. Therefore, option III captures the intended function of shock absorbers in this context.

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.
