What is 'angular acceleration' 🧑‍🔧

After a few coworkers requested my assistance on the matter, I decided to write about "What is 'angular acceleration'". If you're still with doubts, bear with me…

A short answer to this question is…

The time rate of change of angular velocity.

The angular acceleration is the rate of change of angular velocity.

To find the average angular acceleration between two points in time (t 1 & t 2), we need to know the angular velocity at those two points (ω 1 & ω 2).

We can then use an equation to find the average angular acceleration: angular acceleration α = (ω 2 - ω 1) / (t 2 - t 1)

According to wikipedia…

What does wikipedia say about “angular acceleration”? Let’s see:

In physics, angular acceleration refers to the time rate of change of angular velocity. As there are two types of angular velocity, namely spin angular velocity and orbital angular velocity, there are naturally also two types of angular acceleration, called spin angular acceleration and orbital angular acceleration respectively.

I have selected a few questions and answers to help you understand it:

Angular acceleration

When an object is spinning it is accelerating angularly...

If an object is spinning and its speed is changing, it is accelerating angularly. This lesson will go into detail on how to calculate average and instantaneous angular acceleration. Angular motion occurs when an object moves in a rotational path.

What is angular acceleration and its unit...

Angular acceleration is the time rate of change in the angular velocity. It is a pseudovector in 3 dimensions. In the SI unit, we measure it in radians/second squared (rad/s^{2}).

How to calculate angular acceleration...

Obtain radius and tangential acceleration values from the question.

Thanks for reading up to this point and I hope you have great day.
