Question

Quizplus · Accepted Answer

Simple harmonic motion requires a restoring force that is proportional to the displacement from equilibrium and directed towards the equilibrium position. This describes a force that is drawing the body towards the center (the equilibrium position) and increasing with distance away from the center, which is represented by choice D.
