Enter the initial momentum (N-s) and the final momentum (N-s) into the calculator to determine the Impulse From Momentum.

## Impulse From Momentum Formula

The following formula is used to calculate the Impulse From Momentum.

I = Mi – Mf

• Where I is the Impulse From Momentum (N-s)
• Mf is the initial momentum (N-s)
• Mi is the final momentum (N-s)

## How to Calculate Impulse From Momentum?

The following two example problems outline how to calculate the Impulse From Momentum.

Example Problem #1:

1. First, determine the initial momentum (N-s). In this example, the initial momentum (N-s) is given as 30.
2. Next, determine the final momentum (N-s). For this problem, the final momentum (N-s) is given as 15.
3. Finally, calculate the Impulse From Momentum using the equation above:

I = Mi – Mf

Inserting the values from above and solving the equation:

I = 30 – 15 = 15 (N-s)

Example Problem #2:

Using the same process as above, first define the variables required by the formula. In this case, these values are provided as the following:

initial momentum (N-s) = 30

final momentum (N-s) = 10

Entering these values gives:

I =30 -10 = 20 (N-s)
