## Average Angular Acceleration Formula

The following equation is used to calculate the Average Angular Acceleration.

**AAA = (Ai + Af) / 2**

- Where AAA is the Average Angular Acceleration (rad/s^2)
- Ai is the initial angular acceleration (rad/s^2)
- Af is the final angular acceleration (rad/s^2)

## What are the units for Average Angular Acceleration?

In the International System of Units, also known as SI units, the units for Average Angular Acceleration are rad/s^2.

## How to Calculate Average Angular Acceleration?

Example Problem:

The following example problem outlines the steps and information needed to calculate the Average Angular Acceleration.

First, determine the initial angular acceleration. In this example, the initial angular acceleration is calculated or measured to be 100 (rad/s^2).

Next, determine the final angular acceleration. For this problem, the final angular acceleration is determined to be 200 (rad/s^2).

Finally, calculate the Average Angular Acceleration using the formula above:

**AAA = (Ai + Af) / 2**

Inserting the values from above and solving the equation with the imputed values gives:

**AAA = (100+ 200) / 2 = 150 **(rad/s^2)
