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
