## Recoil Momentum Formula

The following equation is used to calculate the Recoil Momentum.

pR = RV * MG

- Where pR is the Recoil Momentum (m/s*kg)
- RV is the recoil velocity (m/s)
- MG is the mass of gun (kg)

To calculate the recoil momentum, multiply the recoil velocity by the mass of the gun.

## What are the units for Recoil Momentum?

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

## How to Calculate Recoil Momentum?

Example Problem:

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

First, determine the recoil velocity. In this example, the recoil velocity is determined to be 48 (m/s).

Next, determine the mass of gun. For this problem, the mass of gun is measured to be 3 (kg).

Finally, calculate the Recoil Momentum using the formula above:

**pR = RV * MG**

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

**pR = 43 * 3 = 129 **(m/s*kg)
