## Linear Impulse Formula

The following formula is used to calculate the Linear Impulse.

JL = LF * dt

- Where JL is the Linear Impulse (N/s)
- LF is the total linear force (N)
- dt is the change in time (s)

To calculate the linear impulse, multiply the linear force by the change in time.

## How to Calculate Linear Impulse?

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

**Example Problem #1:**

- First, determine the total linear force (N). In this example, the total linear force (N) is given as 45.
- Next, determine the change in time (s). For this problem, the change in time (s) is given as 3.
- Finally, calculate the Linear Impulse using the equation above:

JL = LF / dt

Inserting the values from above and solving the equation:

JL = 45 * 3 = 135 (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:

total linear force (N) = 160

change in time (s) = 2

Entering these values gives:

JL = 160 *2 = 320 (N-s)
