When a simple pendulum swings, which of the following quantities does not become zero throughout the oscillation:
Correct answer: A. Mass of pendulum
- A. Mass of pendulum
- B. Momentum of pendulum
- C. Acceleration of pendulum
- D. Velocity of pendulum
Explanation
The mass of the pendulum remains constant throughout its motion. It does not become zero at any point during the oscillation.

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.
