The energy absorbed by a body is __________________ at resonance?
Correct answer: C. Maximum only
- A. Maximum as well minimum
- B. Minimum only
- C. Maximum only
- D. 0
Explanation
At resonance, the driving frequency equals the system's natural frequency, allowing energy transfer to build up most effectively and making the absorbed energy maximum. Minimum absorption occurs away from resonance, not at it. Students may choose a because damping can make the response finite, but damping does not make the absorbed energy both maximum and minimum.

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.
