    Question

    The time period of a pendulum when taken to the Moon would:

    A remain the same Correct Answer Incorrect Answer
    B decrease Correct Answer Incorrect Answer
    C become zero Correct Answer Incorrect Answer
    D increase Correct Answer Incorrect Answer

    Solution

    Since the pendulum rate will increase with an increase in gravity, and local gravity varies with latitude and elevation on Earth, pendulum clocks must be readjusted to keep time after a move. For example, a pendulum clock moved from sea level to 4000 feet will lose 16 seconds per day.
