In S.H.M., we have the conservation of:
Correct answer: C. Total energy
- A. Kinetic energy
- B. Potential energy
- C. Total energy
- D. Mechanical energy
Explanation
Total energy in S.H.M. is the sum of kinetic energy and potential energy of the oscillating object. As the object oscillates, the total energy remains constant (conserved) if there are no external forces or energy losses (e.g., due to friction). The total energy is highest at the equilibrium position, where the kinetic energy is maximum, and potential energy is zero. At the amplitude, the total energy is at its minimum, with zero kinetic energy and maximum potential energy.

About Waves
Progressive waves transfer energy through oscillations, with wavelength, frequency, amplitude and wave speed related by v = fλ; sound speed depends on the medium. Superposition produces interference and stationary waves in strings and organ pipes, while simple harmonic motion describes the oscillation itself and must be distinguished from wave propagation.
