Question

potential and kinetic energy select at what point the pendulum has the greatest potential energy? start

Explanation:

Step1: Recall potential energy formula

The gravitational - potential energy formula is $U = mgh$, where $m$ is mass, $g$ is the acceleration due to gravity, and $h$ is the height above the lowest - point.

Step2: Analyze pendulum motion

The pendulum's mass $m$ and $g$ are constant. The height $h$ is maximum at the extreme positions (the highest points of its swing).

Answer:

The pendulum has the greatest potential energy at the extreme positions (the highest points of its swing).
