In SHM the kinetic energy of the body is maximum when:
Correct answer: A. The body is at mean position
- A. The body is at mean position
- B. The body is at extreme position from the mean
- C. The body is exactly half way down between mean and extreme position
- D. The body is somewhere between mean and extreme position
Explanation
In simple harmonic motion, there is a continuous interchange of kinetic energy and potential energy. At maximum displacement from the equilibrium point, potential energy is a maximum while kinetic energy is zero. At the equilibrium point (mean position) the potential energy is zero and the kinetic energy is a maximum.

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.
