Introduction
Pendulum Period Calculator — Small-angle pendulum period from length and gravity. Enter Length (m), Gravity (m/s²) to get an instant, accurate result.
Formula
Period T = 2π√(L/g), for a simple pendulum under small-angle oscillation.
Step-by-step
- Enter the Length (m).
- Enter the Gravity (m/s²).
- Click Calculate to see your result instantly.
Real-world example
Example: With Length (m) = 1, Gravity (m/s²) = 9.81, the Pendulum Period Calculator gives Period S: 2.0061.
Frequently Asked Questions
Does the pendulum's mass affect the period?
No — for an ideal simple pendulum, only length and gravity affect the period, not the bob's mass.
Is this accurate for large swing angles?
This formula assumes small-angle oscillation; large swings deviate from this simple approximation.
What inputs does the Pendulum Period Calculator need?
You'll need to provide: Length (m), Gravity (m/s²). All fields use sensible defaults, so you can see a working example immediately and then adjust the values to match your own numbers.
How accurate is the Pendulum Period Calculator?
The Pendulum Period Calculator applies the formula exactly as calculated — Period T = 2π√(L/g), for a simple pendulum under small-angle oscillation. — so results are precise for the inputs you provide. Accuracy depends on entering correct, realistic input values.
Is the Pendulum Period Calculator free to use?
Yes, the Pendulum Period Calculator is completely free, requires no signup, and runs instantly in your browser.
About the Pendulum Period Calculator
The Pendulum Period Calculator uses a real, verifiable formula — Period T = 2π√(L/g), for a simple pendulum under small-angle oscillation. — so results are accurate every time, not an approximation.
