## Net Impulse Formula

The following formula is used to calculate the Net Impulse.

**Inet = Fnet * t**

- Where Inet is the Net Impulse (N-s)
- Fnet is the net force (N)
- t is the net change in time (s)

## How to Calculate Net Impulse?

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

**Example Problem #1:**

- First, determine the net force (N). In this example, the net force (N) is given as 315.
- Next, determine the net change in time (s). For this problem, the net change in time (s) is given as 2.
- Finally, calculate the Net Impulse using the equation above:

Inet = Fnet * t

Inserting the values from above and solving the equation:

Inet = 315 * 2 = 630 (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:

net force (N) = 500

net change in time (s) = 20

Entering these values gives:

Inet = 500 * 20 = 10,000 (N-s)
