| n | Position #1 the ball/bob has |

| not starting
falling yet so the |

all in |

| gravitational
potential energy |
|||||||||||
| n | Position #2 the
ball/bob is |
||||||||||
| halfway down,
so total energy |

between PE and |

| KE |

| n | Position #3 the
ball/bob is at |

| the end of its
fall so total |
