Kinetic Energy Formula:
| From: | To: |
The kinetic energy formula calculates the energy of a bullet in foot-pounds based on its mass in grains and velocity in feet per second. It provides an important measure of a bullet's stopping power and terminal performance.
The calculator uses the kinetic energy formula:
Where:
Explanation: The formula converts the standard kinetic energy calculation (0.5*m*v²) into foot-pounds by accounting for the conversion from grains to pounds and the gravitational constant.
Details: Kinetic energy calculation is crucial for understanding bullet performance, terminal ballistics, and effectiveness for different hunting or shooting applications.
Tips: Enter bullet mass in grains and velocity in feet per second. All values must be valid (mass > 0, velocity > 0).
Q1: Why use this specific formula for bullet kinetic energy?
A: This formula is specifically designed for firearms ballistics, converting the standard kinetic energy calculation into the commonly used foot-pounds unit for ammunition performance comparison.
Q2: What are typical kinetic energy values for different calibers?
A: Kinetic energy varies widely by caliber - from around 100-300 ft-lb for small handguns to over 3000 ft-lb for large rifle calibers used in big game hunting.
Q3: How does kinetic energy relate to stopping power?
A: While kinetic energy is one factor in stopping power, bullet design, shot placement, and penetration are equally important considerations for effectiveness.
Q4: Are there limitations to this calculation?
A: This calculation provides theoretical energy at the muzzle; actual energy downrange will be less due to air resistance and other factors.
Q5: Should kinetic energy be the only factor in ammunition selection?
A: No, bullet construction, accuracy, recoil, and intended use should all be considered along with kinetic energy when selecting ammunition.
