True or False

kropot72 · Answer

The restoring force on a simple pendulum is not proportional to the angular displacement theta but to sin theta instead. However for small values of theta, sin theta very nearly equals theta in radians.
Therefore for small displacements a pendulum meets the requirement for simple harmonic motion.
