How to Use This Calculator
- Enter the initial velocity of the bullet (velocity at the start of acceleration)
- Enter the final velocity of the bullet (velocity at the end of acceleration)
- Enter the distance traveled during acceleration (e.g., the length of the barrel)
- Enter the time of acceleration if known
- Click the Calculate button to see the results
Understanding Bullet Acceleration
Bullet acceleration is the rate at which a bullet speeds up as it travels down a firearm's barrel. This calculator uses the kinematic equation:
a = (vf² - vi²) / (2d)
Where a is acceleration, vf is final velocity, vi is initial velocity, and d is distance. This equation assumes constant acceleration, which is a reasonable approximation for the initial portion of bullet travel in a barrel.
Important Notes
- The calculator provides an estimation of average acceleration. Actual acceleration may vary along the barrel length due to changing pressures and other factors.
- The estimated force is calculated assuming a bullet mass of 1kg. For more accurate results, enter the actual bullet mass.
- This calculator uses basic physics equations and does not account for complex factors like air resistance, barrel erosion, or bullet deformation.
