Stopping Power Formula:
| From: | To: |
Stopping power refers to the kinetic energy of a projectile, calculated as half the mass multiplied by the square of its velocity. It represents the energy transferred to the target upon impact and is a key factor in terminal ballistics.
The calculator uses the kinetic energy formula:
Where:
Explanation: The formula calculates the kinetic energy, which directly correlates with the projectile's ability to transfer energy to the target and cause stopping effect.
Details: Accurate stopping power calculation is crucial for ammunition selection, ballistic analysis, self-defense considerations, and understanding terminal performance of projectiles.
Tips: Enter mass in kilograms and velocity in meters per second. Both values must be positive numbers for accurate calculation.
Q1: Why is velocity squared in the formula?
A: Velocity has a squared relationship because kinetic energy increases exponentially with velocity, making it the most significant factor in stopping power.
Q2: What are typical stopping power values for handguns?
A: Common handgun rounds typically produce 300-800 joules of energy, while rifle rounds can exceed 2000-3000 joules depending on caliber and load.
Q3: Is stopping power the only factor in terminal ballistics?
A: No, projectile design, penetration depth, expansion characteristics, and shot placement are equally important factors in terminal effectiveness.
Q4: Can this formula be used for other projectiles?
A: Yes, the kinetic energy formula applies to any moving object, including arrows, slingshot projectiles, and other ballistic devices.
Q5: How does mass affect stopping power compared to velocity?
A: Velocity has a greater impact due to the squared relationship. Doubling velocity quadruples energy, while doubling mass only doubles energy.
