The potential energy at the mean position of a pendulum is:
Correct answer: C. Minimum
- A. Half
- B. Maximum
- C. Minimum
- D. 75%
Explanation
The potential energy at the mean position of a simple pendulum is minimum i.e. zero. At this point, the entire energy is purely kinetic as the system is at its maximum speed.

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.
