E)when the potential energy is a zero

Question

Quizplus · Accepted Answer

In simple harmonic motion, the speed is greatest when the object passes through the equilibrium position, where the potential energy is at a minimum (or zero) and the kinetic energy is at a maximum. This corresponds to when the magnitude of the acceleration is a minimum (C) because acceleration is zero at the equilibrium position, and when the potential energy is zero (E), indicating maximum kinetic energy and thus maximum speed.
