Enter the bullet mass and the bullet velocity into the calculator to determine the Bullet Momentum. 

Bullet Momentum Formula

The following equation is used to calculate the Bullet Momentum.

pB = Bm*BV
  • Where pB is the Bullet Momentum (m/s*kg)
  • Bm is the bullet mass (kg)
  • BV is the bullet velocity (m/s)

To calculate the bullet momentum multiply the bullet mass by the bullet velocity.

What are the units for Bullet Momentum?

The most common units for Bullet Momentum are m/s*kg.

How to Calculate Bullet Momentum?

Example Problem:

The following example problem outlines the steps and information needed to calculate the Bullet Momentum.

First, determine the bullet mass. In this example, the bullet mass is determined to be 21 (kg).

Next, determine the bullet velocity. For this problem, the bullet velocity is measured to be 5 (m/s).

Finally, calculate the Bullet Momentum using the formula above: 

pB = Bm*BV

Inserting the values from above and solving the equation with the imputed values gives: 

pB = 21*5 =105 (m/s*kg)
