Simple Pendulum Period Calculator

Calculate the period (T), frequency (f), or string length (L) of a simple pendulum using the small-angle approximation formula. Physics calculator for high school and university students studying mechanics, oscillations, and wave theory. Enter any two values to find the third.

Pendulum Period Formula

T = 2π √(L/g)

Keterangan:

  • T
    Period (seconds)
  • L
    String Length (meters)
  • g
    Gravitational Acceleration (m/s²)
  • f
    Frequency (Hz) = 1/T

Contoh Perhitungan

Pendulum Period Example

Soal:

A string is 1 meter long. What is the period?

Penyelesaian:
  1. 1.L = 1 m
  2. 2.g = 9.8 m/s²
  3. 3.T = 2π √(1/9.8)
Hasil:2.007 seconds

One full back-and-forth swing takes about 2 seconds.

Pertanyaan yang Sering Diajukan (FAQ)

Does mass affect the period?
No—for small angles, the bob's mass does not affect the pendulum period.
When does this formula apply?
It applies for small angular displacements (< 15°) and when the string is considered massless.
