Question:

(a) If a pendulum clock were taken to the Moon, where the acceleration due to gravity is only one-sixth (assume the figure to be exact) that on the Earth, will the period of vibration (1) increase, (2) remain the same, or (3) decrease? Why?
(b) If the period on the Earth is 2.0 s, what is the period on the Moon?
