The image shows a pendulum in simple harmonic motion. The pendulum starts at A and swings to E. An illustration of a pendulum at 5 different positions. The central position, the equilibrium position is labeled C. The two positions on the left are labeled a and B respectively. The two positions on the right are labeled D and E respectively. All positions are equally spaced. Which labels are correct? Check all that apply. E: Net force is zero. D: Velocity is decreasing. Acceleration is increasing. A: Velocity is zero. C: Acceleration is maximum. B: Velocity is decreasing. Net force is decreasing. E: Velocity is maximum.
