The Dynamics of Rotating Rigid Bodies

This collection of visuals outlines the comprehensive physics of rotating systems, moving from fundamental vector calculus to orbital mechanics. It begins by defining the velocity field (which is incompressible and represents vorticity) and the acceleration field (which relates to centripetal and tangential forces). These kinematics are then bridged via Python simulations to demonstrate real-world applications, such as a bead on a rotating rod or stable celestial orbits. Central to this framework is the derivation of a centripetal potential function, which proves that the centripetal acceleration field is conservative ( $\nabla \times a _{ c }=0$ ). Ultimately, the materials show how these potential fields create a "stable valley trap" in celestial mechanics, allowing for the application of the Work-Energy Theorem and the conservation of energy within rotating reference frames.
