Does rolling friction depend on the surface area? In other words, the size of the object placed? If I had a block and sphere of the same mass. Without static and kinetic friction coming into play. Which would experience greater rolling friction if they were on the same incline and of the same material and mass? If I had a similar scene with a cube and cuboid (The base area of the cuboid is more, they are made of same materials and have the same mass.). Which would go down first if kinetic friction is considered? Assuming no toppling.
