The given figure shows kinetic, potential and total energies for a SHM.
Correct answer: A. A
- A. A
- B. B
- C. C
- D. D
Explanation
The potential energy stored in a spring is given by Hooke's Law, which states that the force exerted by a spring is directly proportional to the displacement from its equilibrium position. At the equilibrium position, x is zero, and therefore, the potential energy U is also zero. Since the kinetic energy depends upon velocity, it is maximum at mean position.

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.
