Simple harmonic oscillations can be modeled by the projection of circular motion at constant angular velocity onto a diameter of the circle. When this is done, the analog along the diameter of the acceleration of the particle executing simple harmonic motion is
a. the displacement from the center of the diameter of the projection of the position of the particle on the circle.
b. the projection along the diameter of the velocity of the particle on the circle.
c. the projection along the diameter of tangential acceleration of the particle on the circle.
d. the projection along the diameter of centripetal acceleration of the particle on the circle.
e. meaningful only when the particle moving in the circle also has a non-zero tangential acceleration.
