Question

Quizplus · Accepted Answer

At the bottom of its swing, the bob of a simple pendulum has its maximum kinetic energy because the gravitational potential energy is zero at this point, meaning all the potential energy has been converted into kinetic energy. As the bob moves up, its kinetic energy decreases and potential energy increases until it reaches the top of the swing, where potential energy is at its maximum and kinetic energy is at its minimum. Then, as the bob goes back down, potential energy decreases and kinetic energy increases again. Therefore, option B is the correct choice.
