First time to physics Stack Exchange and I'm about to show my extreme lack of physics knowledge. I've only been through Physics 121, particle physics. So, bear with me!
So an object, a sphere for simplicity, is rotating. I learned the formulae for angular momentum, kinetic energy, etc. but conceptually, it seems like those formulae are a macro-level representation of the complex dynamics and micro-interactions of the various particles that make up the sphere. There are other forces at work keeping the sphere's particles in sphere-shape (be it gravity, molecular bonds, whatever). Without these forces, each of the particles would fly off tangentially, correct?
In these particles' "micro-interactions" (there has to be a better description than that), is there potential for energy loss? Would this energy loss rob the sphere of its rotational kinetic energy?
