When a body is performing S.H.M then at its extreme position?
Correct answer: C. Velocity is a zero
- A. Displacement is zero
- B. Amplitude is zero
- C. Velocity is a zero
- D. P.E is zero
Explanation
Correct option c) Velocity is zero: At the extreme positions (the points where the body momentarily stops before changing direction) in S.H.M, the velocity of the body is zero. This is because the velocity changes sign at these points, going from positive to zero to negative (or vice versa), indicating that the body is momentarily at rest.

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.
