In the case of a harmonic oscillator total energy remains:
Correct answer: C. Constant
- A. Variable
- B. Infinity
- C. Constant
- D. Zero
Explanation
During the oscillations, the total energy is constant and equal to the sum of the potential energy and the kinetic energy of the system, ETotal=12kx2+12mv2=12kA2.Hence total energy of the particle performing SHM is conserved.

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.
