Simple Pendulum Calculator

Formula

T = 2π√(L/g), where L is pendulum length and g is gravitational acceleration.

Compute the period of a simple pendulum using the small-angle approximation T = 2pi*sqrt(L/g). Works for any gravitational environment including the Moon or Mars.

Common use cases:

  • Clock design
  • Physics lab experiments
  • Gravity measurement
