Angular Acceleration Introduction

The video tutorial covers the concept of average acceleration, starting with linear acceleration and its equation. It then introduces angular acceleration, symbolized by the Greek letter alpha, humorously referred to as the 'fishy thing.' The tutorial explains the equation for angular acceleration as the change in angular velocity over time and discusses its units, primarily radians per second squared. Various examples of objects experiencing angular acceleration are provided, such as bike tires and ceiling fans. The video concludes with a note on the direction of angular acceleration, promising to cover it in detail later.

What are the units for angular acceleration if angular velocity is in radians per second?

Can you name some objects that can have angular acceleration?
