# Pendulum Length Calculator

want to calculate pendulum length? just enter Acceleration due to gravity (m/s^{2}) Frequency (Hz) in the input fields of this calculator and the accurate Pendulum Length (m) in the result field. Whether you’re a student, educator this tool will certainly will make your work easier.

### What is a Pendulum Length?

A pendulum’s length is the distance between the point of suspension and its center of mass. This length determines the period of the swing, which is the time it takes to complete one full oscillation.

### Using Guide

To use the Pendulum Length Calculator is easy. Just follow these steps:

**Enter the acceleration due to gravity (g) in m/s².****Enter the frequency (f) in Hz.****Enter the pendulum length (PL) in meters.**

You need to provide any two of these values to calculate the third. For example, if you know the gravity and frequency, you can find the pendulum length.

**Example Input Values:**

- Gravity: 9.8 m/s²
- Frequency: 0.5 Hz
- Pendulum Length: (leave blank for the calculator to find)

### How to Calculate Pendulum Length

The formula to calculate the pendulum length is:

**Formula:**

$PL = \frac{g}{4 \cdot \pi^2 \cdot f^2}$

**Variables:**

Variable | Description |
---|---|

PL | Pendulum Length (meters) |

g | Acceleration due to gravity (m/s²) |

f | Frequency (Hz) |

#### Calculation:

Let’s say we have:

- Acceleration due to gravity (g) = 9.8 m/s²
- Frequency (f) = 0.5 Hz

To calculate the pendulum length (PL):

1. Square the frequency: $0.5^2 = 0.25$

2. Multiply by $4 \cdot \pi^2$: $4 \cdot (3.14^2) = 39.48$

3. Divide gravity by this product: $9.8 / 39.48 = 0.248$

So, the pendulum length is approximately 0.248 meters.

### Calculation Examples

Calculation Type | Example Values |
---|---|

Basic |
g = 9.8, f = 0.5 |

Advanced |
g = 9.8, f = 0.5, PL = 0.248 |
