1. What is Kinetic Energy?

Kinetic energy is the energy possessed by an object due to its motion. For bullets, it's a key factor in determining stopping power and terminal ballistics.

2. How Does the Calculator Work?

The calculator uses the kinetic energy equation:

Where:

• \( KE \) — Kinetic energy (Joules)
• \( m \) — Mass of the bullet (kilograms)
• \( v \) — Velocity of the bullet (meters per second)

Explanation: The energy increases with the square of velocity, making velocity more significant than mass in energy calculations.

3. Importance of Kinetic Energy Calculation

Details: Kinetic energy helps assess a bullet's potential effectiveness for hunting or self-defense, and is often used in firearm regulations.

4. Using the Calculator

Tips: Enter bullet mass in kilograms and velocity in meters per second. For grains and fps, convert first (1 grain = 0.0000648 kg, 1 fps = 0.3048 m/s).

5. Frequently Asked Questions (FAQ)

Q1: What's a typical KE for handgun rounds?
A: Common handgun rounds range from 300-800 J, while rifle rounds often exceed 1000 J.

Q2: How does KE relate to stopping power?
A: While important, KE alone doesn't determine stopping power - bullet design, shot placement, and other factors matter too.

Q3: What's the minimum KE for hunting?
A: Recommendations vary by game, but typically 1000 J for deer, 1500 J for larger game.

Q4: How accurate is this calculation?
A: It provides theoretical maximum KE. Actual on-target energy may be less due to air resistance.

Q5: Why use joules instead of foot-pounds?
A: Joules are the SI unit. To convert to ft-lbs, divide by 1.3558.
