A pendulum on the Earth has a period T.The acceleration of due to gravity on Mars is less than that on the Earth,and the acceleration due to gravity on the Moon is even less.Where would the period of an identical pendulum be the least?
A)on the Earth
B)on the Moon
C)on Mars
D)The period of a pendulum would be the same on the Earth,Moon,and Mars since the period depends on the pendulum's length which is the same for identical pendula.

Quizplus · Accepted Answer

The period of a pendulum is given by $T = 2\pi\sqrt{\frac{L}{g}}$, where $L$ is the length of the pendulum and $g$ is the acceleration due to gravity. Since $g$ is highest on Earth compared to Mars and the Moon, the period $T$ is least on Earth.
