(05.01 LC) A pendulum is shown pulled back and labeled A. Another pendulum is shown hanging straight down labeled B. As the pendulum swings from position B to position A, which of the following best describes the motion (neglect friction)? (4 points) The bob is speeding up as the kinetic energy decreases. The bob is slowing down as the kinetic energy increases. The bob is speeding up as the potential energy decreases. The bob is slowing down as the potential energy increases. 2.
