In simple harmonic motion, when is the speed the greatest?
I. when the magnitude of the force is minimum
II. when the potential energy is maximum.
III. when the potential energy is zero.
IV. when the displacement is maximum.

In simple harmonic motion, the speed is greatest at that point in the cycle when

(a) the magnitude of the acceleration is a maximum.

(b) the magnitude of the acceleration is a minimum.

(c) the displacement is a maximum.

(d) the kinetic energy is a minimum.
