Calculation Formula

The period of a simple pendulum is given by:

T = 2π√(L/g)

Where:
T = Period of the pendulum (seconds)
L = Length of the pendulum (meters)
g = Acceleration due to gravity (m/s²)

How to Use the Calculator

  1. Enter the length of the pendulum in meters in the "Length (L) in meters" field.
  2. Enter the acceleration due to gravity in m/s² in the "Acceleration due to gravity (g) in m/s²" field. The default value is 9.81 m/s², which is the standard value on Earth's surface.
  3. Click the "Calculate" button to compute the period of the pendulum.
  4. The period of the pendulum will be displayed in the "Period (T) in seconds" field.
  5. Click the "Reset" button to clear all input and result fields.

Working Principle

A simple pendulum consists of a mass (bob) attached to a string or rod that is fixed at one end. When the pendulum is displaced from its equilibrium position and released, it swings back and forth under the influence of gravity.

The period of a simple pendulum is the time it takes for the pendulum to complete one full oscillation. The period depends only on the length of the pendulum and the acceleration due to gravity, and is independent of the mass of the bob.

The formula for the period of a simple pendulum is:

T = 2π√(L/g)

Where:

  • T is the period of the pendulum (in seconds)
  • L is the length of the pendulum (in meters)
  • g is the acceleration due to gravity (in m/s²)
