## Total Impulse Formula

The following formula is used to calculate the Total Impulse.

Itotal = Σ Ft * dt

- Where Itotal is the Total Impulse (N-s)
- Σ Ft is the sum of the thrust forces (N)
- dt is the time (seconds)

To calculate the total impulse, multiply the sum of the thrust forces by the time.

## How to Calculate Total Impulse?

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

**Example Problem #1:**

- First, determine the sum of the thrust forces (N). In this example, the sum of the thrust forces (N) is given as 250.
- Next, determine the time (seconds). For this problem, the time (seconds) is given as 3.
- Finally, calculate the Total Impulse using the equation above:

Itotal = Σ Ft * dt

Inserting the values from above and solving the equation:

Itotal = 250 * 3 = 750 (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:

sum of the thrust forces (N) = 150

time (seconds) = 4

Entering these values gives:

Itotal = 150* 4 = 600 (N-s)
