Period of a 1 m Pendulum on Mars
On Mars (g = 3.72 m/s²), a 1 m pendulum has a period of approximately 3.26 seconds.

Mars's weaker gravity slows the pendulum by more than 60% compared to Earth — useful for thinking about clock design on other planets.
Frequently asked questions
- What is the period of a 1-metre pendulum on Earth?
- Approximately 2.006 seconds, which is why 1-metre pendulums were historically used in grandfather clocks (half-period ≈ 1 s per swing).
- Does mass affect the period?
- No — the small-angle period T = 2π√(L/g) is entirely independent of mass.
