The video tutorial explains angular velocity, focusing on calculating it at two points, A and B, on a circle. It discusses the relationship between angles at the center and circumference, using theta notation to differentiate with respect to time. The tutorial emphasizes the importance of distinguishing between constant and variable angles to accurately determine angular velocity.
