The physics of rotation: understanding angular velocity and circular motion

Angular velocity and speed | Uniform circular motion and gravitation | AP Physics 1 | Khan Academy · 7:30 · Video: Khan Academy · Watch at the source

In short: Explore the fundamental mechanics governing how objects move in circles. This video from Khan Academy breaks down the relationship between angular velocity, uniform circular motion, and gravitation for AP Physics students.

Led by former mechanical engineer and physics teacher Sean, this lesson provides a structured look at rotational dynamics. It covers how objects maintain constant speeds while moving along curved paths—a concept essential for understanding both simple orbits and complex machinery.

The content is designed to help students master the mathematical and conceptual frameworks of AP Physics 1, specifically focusing on how gravitational forces dictate circular motion.
