Pendulum Period Calculator – T = 2π√(L/g)
Calculate the period of a simple pendulum using T = 2π√(L/g).
How It Works
Enter the pendulum length in meters. Gravitational acceleration defaults to 9.81 m/s² (Earth), but you can change it for other planets. The result is the period in seconds.
Formula
T = 2π × √(L ÷ g)
Frequently Asked Questions
Does a pendulum's mass affect its period?
No. For a simple pendulum, only length and gravitational acceleration affect the period. Mass cancels out in the formula.
What is the period of a 1-meter pendulum?
T = 2π√(1/9.81) ≈ 2.006 seconds on Earth.
