What is true about the acceleration of an object undergoing simple harmonic motion?
Correct answer: A. Acceleration is minimum when velocity is maximum
- A. Acceleration is minimum when velocity is maximum
- B. acceleration is proportional to the frequency of oscillation
- C. acceleration is in opposite direction to its velocity
- D. acceleration is minimum when potential energy is maximum
Explanation
This statement is true. In SHM, when the object passes through the equilibrium position, its velocity is at its maximum, and the acceleration is zero. Conversely, at the maximum displacement (amplitude), the velocity is zero, and the acceleration is at its maximum, directed towards the equilibrium 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.
