What is Foot-Pounds Energy (FPE)?

Foot-Pounds Energy (FPE) is a measure of the kinetic energy contained in a projectile. It is calculated using the velocity and weight of the projectile. This metric is commonly used in ballistics to understand the impact energy of a projectile.

Example Calculation 1

Let's assume the following values:

Using the formula:

\[ FPE = \frac{3000^2 \times 150}{450240} = 3000 \text{ foot-pounds} \]

The Foot-Pounds Energy is 3000 foot-pounds.

Example Calculation 2

Let's assume the following values:

Using the formula:

\[ FPE = \frac{2500^2 \times 200}{450240} = 2777.78 \text{ foot-pounds} \]

The Foot-Pounds Energy is 2777.78 foot-pounds.
