Kinetic Energy Formula:
| From: | To: |
The kinetic energy formula (KE = 1/2 × m × v²) calculates the energy of a moving object, where m is mass and v is velocity. For bullets, this represents the energy delivered to the target upon impact.
The calculator uses the kinetic energy equation:
Where:
Explanation: The equation shows that kinetic energy increases with the square of velocity, making velocity the most significant factor in bullet energy.
Details: Calculating bullet kinetic energy is crucial for understanding terminal ballistics, hunting effectiveness, and self-defense round selection. Higher energy typically means greater stopping power and penetration.
Tips: Enter bullet mass in kilograms and velocity in meters per second. For imperial units, convert grains to kilograms (1 grain = 0.0000648 kg) and feet per second to m/s (1 fps = 0.3048 m/s).
Q1: Why is kinetic energy important for bullets?
A: Kinetic energy determines the bullet's ability to transfer energy to the target, affecting penetration, expansion, and stopping power.
Q2: What is a typical kinetic energy range for handgun rounds?
A: Most handgun rounds range from 300-800 Joules, with some magnum rounds exceeding 1000 Joules.
Q3: How does rifle ammunition compare to handgun ammunition?
A: Rifle rounds typically have much higher velocities, resulting in significantly greater kinetic energy, often ranging from 2000-4000+ Joules.
Q4: Is kinetic energy the only factor in stopping power?
A: No, bullet design, shot placement, and target characteristics also significantly affect stopping power and terminal performance.
Q5: How accurate is this calculation for real-world ballistics?
A: While the formula accurately calculates kinetic energy, real-world performance also depends on factors like bullet construction, aerodynamics, and environmental conditions.
