Quizplus · Accepted Answer

The graph of kinetic energy as a function of displacement from equilibrium for a mass attached to a spring displacing from -x to x should be a symmetric parabola, with the minimum point at 0 displacement (equilibrium). Graph D is the only one that fits this description. Graphs A, B, and E have incorrect shapes, while graphs C has two minima instead of one.
