Rolling down an incline: why does friction not reduce the energy, and which shape reaches first?
I'm repeating, and rotational motion is the chapter I have always handled with formulas, not understanding. This time I want the concept. Pure rolling means v=\omega R for the centre. Total KE =\tfrac12mv^2+\tfrac12I\ome

Rotational motion feels like a pile of formulas. Is there an easier way into moment of inertia and rolling?
Rotation looks like a new subject, but it is mostly linear motion in a different costume. Here is a way in that cuts down what you need to memorise.

The ring always loses: what one rolling-race question taught me about rotational motion
I lost three marks on a "which reaches the bottom first" question, then spent a weekend with a plank and four tins. This is the whole idea in one place.
