Pendulum Period

Classical Mechanics Level 1

What is the ratio of the period of a pendulum on Mars to the period of the same pendulum on Earth?

Details and assumptions

Gravity on Earth is 9.8 m / s 2 9.8~m/s^{2}

Gravity on Mars is 3.71 m / s 2 3.71~m/s^{2}


The answer is 1.625.

We know that the time period of a pendulum is , T = 2 π l g T=2π\sqrt{\frac{l}{g}}

Ratio of time period of Mars to that of moon will be,

= 9.8 3.71 \sqrt{\frac{9.8}{3.71}}

= 1.625 1.625
