Momentum Gain Formula

The following equation is used to calculate the Momentum Gain.

pG = m* (FV - IV)

• Where pG is the Momentum Gain (m/s*kg)
• m is the mass of the object (kg)
• FV is the final velocity (m/s)
• IV is the initial velocity (m/s)

To calculate the momentum gain, multiply the mass of the object by the change in velocity.

What are the units for Momentum Gain?

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

How to Calculate Momentum Gain?

Example Problem:

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

First, determine the mass of the object. In this example, the mass of the object is determined to be 10 (kg).

Next, determine the final velocity. For this problem, the final velocity is measured to be 20 (m/2).

Next, determine the initial velocity. In this case, the initial velocity is found to be 10 (m/s).

Finally, calculate the Momentum Gain using the formula above: 

pG = m* (FV – IV)

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

pG = 10* (20 – 10) =100 (m/s*kg)
