Foot Pounds of Energy Calculator
To calculate foot-pounds of energy, multiply the mass (M) by the gravitational acceleration (g), then multiply by the bullet speed (BS) squared, and divide by 450,437.
The Foot Pounds of Energy (FPE) Calculator works to calculate the energy produced by an object based on its mass, speed, and gravitational acceleration.
This calculation is crucial in fields like physics and engineering, particularly for understanding the kinetic energy of objects in motion. For example, in the case of a bullet, the energy it produces upon impact can be calculated using this formula.
Formula
| Variable | Description |
|---|---|
| E | Foot pounds of energy (energy produced) |
| M | Mass (in pounds) |
| g | Gravitational acceleration (in feet per second squared) |
| BS | Bullet speed (in feet per second) |
Solved Calculations
Example 1:
For instance, if the mass (M) is 2 pounds, the gravitational acceleration (g) is 32.2 ft/s², and the bullet speed (BS) is 1200 ft/s, the energy (E) is:
| Step | Calculation |
|---|---|
| Mass (M) | 2 pounds |
| Gravitational Acceleration (g) | 32.2 ft/s² |
| Bullet Speed (BS) | 1200 ft/s |
| Result | = 332.7 foot-pounds |
Answer: The foot pounds of energy is 332.7.
Example 2:
Similarly, if the mass is 3 pounds, the gravitational acceleration is 32.2 ft/s², and the bullet speed is 1000 ft/s, the energy is:
| Step | Calculation |
|---|---|
| Mass (M) | 3 pounds |
| Gravitational Acceleration (g) | 32.2 ft/s² |
| Bullet Speed (BS) | 1000 ft/s |
| Result | = 214.8 foot-pounds |
Answer: The foot pounds of energy is 214.8.
