I was referring to, rolling friction being illuminated, but still the force to accelerate the mass translationally and rotationally and then to decelerate it, would be needed to calculate the work done over time. (power).haruspex said:It's not the shape, more the rigidity.
Real world objects are not completely rigid. A tyre deforms as it rotates, producing a flat area in contact with the road. This constant deformation takes work. But rolling resistance is not limited to that. It might be mostly that, but the term is a catch-all encompassing other losses as such axle friction.
