SHM in a Pendulum. The motion of a simple pendulum is very close to Simple Harmonic Motion (SHM). SHM results whenever a restoring force is proportional to the displacement, a relationship often known as Hooke's Law when applied to springs. F = -kx. Where F is the restoring force, k is the spring constant, and x is the displacement.
