Enter the mass, velocity, and radius into the calculator to determine the centrifugal g-forces acting on the object.

## Centrifugal G Force Formula

The following equation is used to calculate the Centrifugal G Force.

Fgc = [ V^2 / r ] / G

• Where Fgc is the number of g-forces of acceleration seen by the rotating object
• V is the tangential velocity of the object (m/s)
• r is the radius of rotation (m)
• G is the acceleration due to gravity = 9.81 m/s^2

## What is a Centrifugal G Force?

Definition:

A centrifugal G-force measures the acceleration seen by a rotating object relative to the acceleration due to gravity. In other words, it’s the object’s acceleration divided by the acceleration due to gravity.

## How to Calculate Centrifugal G Force?

Example Problem:

The following example outlines the steps and information needed to calculate the Centrifugal G Force.

First, determine the tangential velocity of the object. In this example problem, this is measured to be 50 m/s.

Next, determine the radius of the rotation. This is measured to be 3m.

Finally, calculate the number of G-forces using the formula above:

Fgc = [ V^2 / r ] / G

Fgc = [ 50^2 / 3 ] / 9.81

Fgc = 84 .95 Gs
