If you think about an object in simple harmonic motion (picture a mass on the end of a spring), it will have maximum velocity as it pases the equilibrium position, and at the max displacements it will have minimum velocity (as it is stantionary so zero velocity). This means the kinetic energy at max displacements is zero.

Since kinetic energy is max at the equilibrium position, potential energy is min at the equilibrium position
