Which graph in SHM shows the K.E of a body:
Correct answer: A. Option A
- A. Option A
- B. Option B
- C. Option C
- D. Option D
Explanation
The K.E of an oscillating body is maximum at the equilibirum position because speed is maximum at that point, and is 0 at the extreme positions because speed is 0 at those points. Graph B depcits the P.E, while Graph C depicts the TOTAL energy.

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.
