Question

A pendulum undergoes _______ motion​

Answer 1

Explanation:

Any pendulum undergoes simple harmonic motion when the amplitude of oscillation is small. The pendulum still oscillates, but the motion is no longer simple harmonic motion because the angular acceleration is not proportional to the negative of the angular displacement.

Answer 2

Answer:

Any pendulum undergoes simple harmonic motion when the amplitude of oscillation is small. What happens for large amplitudes? The pendulum still oscillates, but the motion is no longer simple harmonic motion because the angular acceleration is not proportional to the negative of the angular displacement.
