1. What is Stopping Power?

Stopping Power represents the adjusted kinetic energy of a projectile, taking into account its ballistic coefficient. It provides a more accurate measure of a projectile's effectiveness than basic kinetic energy alone by incorporating its aerodynamic efficiency.

2. How Does the Calculator Work?

The calculator uses the stopping power formula:

\[ \text{Stopping Power} = \frac{1}{2} \times m \times v^2 \times BC \]

Where:

\( m \) — Mass of the projectile (kg or lb)
\( v \) — Velocity of the projectile (m/s or ft/s)
\( BC \) — Ballistic coefficient (dimensionless)

Explanation: The formula calculates the basic kinetic energy (½mv²) and adjusts it by the ballistic coefficient to account for the projectile's ability to overcome air resistance.

3. Importance of Stopping Power Calculation

Details: Stopping power is crucial for evaluating terminal ballistics performance, comparing different ammunition types, and predicting effectiveness for hunting, self-defense, or tactical applications.

4. Using the Calculator

Tips: Enter mass in kg or lb, velocity in m/s or ft/s, and ballistic coefficient (typically between 0.1-1.0). All values must be positive numbers. The calculator automatically converts between unit systems.

5. Frequently Asked Questions (FAQ)

Q1: What is ballistic coefficient?
A: Ballistic coefficient (BC) is a measure of a projectile's ability to overcome air resistance compared to a standard projectile. Higher BC means better aerodynamic efficiency.

Q2: How does BC affect stopping power?
A: Higher BC projectiles retain velocity and energy better over distance, resulting in greater stopping power at longer ranges.

Q3: What are typical BC values?
A: BC values range from about 0.1 for poor aerodynamics to over 0.8 for highly efficient long-range projectiles.

Q4: Why calculate stopping power instead of just kinetic energy?
A: Stopping power provides a more realistic measure of terminal effectiveness by accounting for both energy and the projectile's ability to maintain that energy through air resistance.

Q5: Can this calculator be used for all projectile types?
A: The calculator works for any projectile where mass, velocity, and ballistic coefficient are known, including bullets, arrows, and other ballistic objects.
