A pendulum is attached to a fixed point and then released with a swinging motion. Three positions (1, 2, and 3) are marked on the path of the pendulum as it swings. If the energy of the pendulum follows the Law of Conservation of Energy, which table could represent the kinetic and potential energy values at the three positions?
