For a system undergoing simple harmonic motion, which of the following statements is true? (The equilibrium point refers to the particle's average location, which is a point of static equilibrium; the turning points are points where the particle's motion changes direction. Assume that the potential energy is zero at equilibrium.)
A.
The kinetic energy is maximized at the turning points.
B.
The potential energy is maximized at the equilibrium points.
C.
The work done by the restoring force is equal to the change in the potential energy.
D.
The kinetic energy equals the potential energy four times during each period.
E.
none of the above
