When will the oscillations stop in the absence of resistive forces?
Correct answer: A. Never
- A. Never
- B. After 10 minutes
- C. In 10 minutes
- D. Immediately
Explanation
In the absence of resistive forces, the oscillations will never stop. In simple harmonic motion, such as oscillations of a mass-spring system or a pendulum, the absence of resistive forces means that there is no external force acting to dissipate the energy of the oscillation. As a result, the system will continue to oscillate indefinitely without losing energy or coming to a stop.

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.
