Recoil Momentum Calculator

How to Use This Calculator

1. Enter the mass of the projectile in kilograms (kg). For example, a standard 9mm bullet has a mass of approximately 0.009 kg.
2. Enter the velocity of the projectile in meters per second (m/s). For example, a 9mm pistol might fire bullets at 350 m/s.
3. Click the "Calculate" button to compute the recoil momentum.
4. The result will be displayed in kilogram-meters per second (kg·m/s).

Understanding Recoil Momentum

Recoil momentum is the backward momentum generated when a projectile is fired from a gun. According to Newton's Third Law of Motion, for every action, there is an equal and opposite reaction.

The formula used is p = m × v, where p is momentum, m is mass, and v is velocity. This means that even if a bullet has a small mass but high velocity, it can still generate significant recoil momentum.

Practical Applications

This calculator can help firearm enthusiasts understand the recoil characteristics of different ammunition. Higher momentum generally means more forceful recoil, which can affect shooter comfort and accuracy.

Example Calculation

If a 0.22 caliber bullet (mass = 0.003 kg) is fired at 400 m/s, the recoil momentum would be:
p = 0.003 kg × 400 m/s = 1.2 kg·m/s
