* Kinetic energy is at its maximum. The pendulum is moving at its fastest speed at this point, so it has the highest kinetic energy.
* Potential energy is at its minimum. The pendulum is at its lowest point, so it has the least amount of gravitational potential energy.
Think of it like this:
* At the top of its swing: The pendulum has maximum potential energy (due to its height) and minimum kinetic energy (since it momentarily stops).
* At the bottom of its swing: The pendulum has minimum potential energy (at its lowest point) and maximum kinetic energy (because it's moving fastest).
