In this episode of The Dead Scientists, we dive into the mechanics of rotation in two dimensions. Join us as we explore the fundamental concept of the center of mass and its crucial role in analyzing the motion of complex objects, especially rigid bodies.

We'll delve into the kinematics and dynamics of rotation, defining key quantities like angular velocity, angular acceleration, and torque. Discover how these concepts parallel those of linear motion, providing a comprehensive framework for understanding how objects spin and rotate.

We'll emphasize the conservation of angular momentum—a powerful principle governing the rotational motion of particle systems. Learn how this conservation law explains phenomena from spinning ice skaters to orbiting planets.

Finally, we'll connect these ideas to the moment of inertia, a measure of an object's resistance to changes in its rotational state. By understanding moment of inertia, you'll gain insights into why some objects are easier to spin than others.

Whether you're a physics enthusiast or just curious about the forces that make things spin, this episode offers a fascinating journey into the mechanics of rotation, illuminated by Feynman's exceptional ability to make complex ideas accessible.
