## Angular Impulse Formula

The following formula is used to calculate the Angular Impulse.

**Ja = T * dt**

- Where Ja is the Angular Impulse (N-m-s)
- T is the torque (N-m)
- dt is the change in time (s)

## How to Calculate Angular Impulse?

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

**Example Problem #1:**

- First, determine the torque (N-m). In this example, the torque (N-m) is given as 40.
- Next, determine the change in time (s). For this problem, the change in time (s) is given as 5.
- Finally, calculate the Angular Impulse using the equation above:

Ja = T * dt

Inserting the values from above and solving the equation:

Ja = 40 * 5 = 200 (N-m-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:

torque (N-m) = 75

change in time (s) = 3

Entering these values gives:

Ja = 75 *3 = 225 (N-m-s)
