Impact G Force Calculator

Formula

The formula to calculate the Impact G Force (IGF) is:

\[ IGF = \left[\frac{1}{2} \cdot \frac{v^2}{d}\right] / 9.81 \]

Where:

\( IGF \) is the Impact G Force
\( v \) is the velocity of impact (m/s)
\( d \) is the distance traveled during impact (meters)

What is an Impact G Force?

Definition: An impact G force is the number of units of acceleration experienced during an impact relative to the acceleration due to gravity on Earth. In other words, this is the acceleration during impact divided by 9.81 meters per second squared.

Example Calculation

Let's assume the following values:

Velocity of Impact (v) = 20 m/s
Distance Traveled During Impact (d) = 0.5 meters

Using the formula to calculate the Impact G Force:

\[ IGF = \left[\frac{1}{2} \cdot \frac{20^2}{0.5}\right] / 9.81 = \left[\frac{1}{2} \cdot \frac{400}{0.5}\right] / 9.81 = \left[400\right] / 9.81 \approx 40.77 \text{ G} \]

The Impact G Force (IGF) is approximately 40.77 G.
