If you take a given pendulum to the Moon, where the acceleration of gravity is less than on Earth, the resonant frequency of the pendulum will
A) increase.
B) decrease.
C) not change.
D) become zero.
E) either increase or decrease; it depends on its length to mass ratio.

Question

Quizplus · Accepted Answer

The resonant frequency of a pendulum is determined by its length and the acceleration due to gravity. As the acceleration due to gravity is less on the Moon than on Earth, the resonant frequency of the pendulum will decrease as the frequency is inversely proportional to the square root of the acceleration due to gravity. This means that the length of the pendulum would need to be shortened to increase the resonant frequency on the Moon, but this is not an option in the given choices.
