Pendulum Period Calculator
Calculate the period, frequency, and oscillation properties of a simple pendulum using the formula T = 2π√(L/g).
Pendulum Parameters
Length from pivot point to center of mass
Default: 9.81 m/s² (Earth)
Pendulum Formula
T = 2π√(L/g)
where: T = period, L = length, g = gravity
Note
This formula assumes small angles (< 15°). For large angles, the period increases slightly.
Example Pendulums
About Pendulum Motion
A simple pendulum exhibits simple harmonic motion. The period depends only on length and gravity, not on mass or amplitude (for small angles).
- Period independent of mass
- Period proportional to √L
- Period inversely proportional to √g
Applications
- Timekeeping (clocks)
- Measuring gravity
- Seismometers
- Metronomes
- Physics demonstrations
