Solid shapes that can slide and roll include cylinders, spheres, and cones. Cylinders can roll along their curved surface, while spheres can roll in any direction due to their uniform curvature. Cones can roll on their circular base, although their movement is limited to a specific direction. In contrast, cubic shapes can slide but do not roll effectively due to their flat surfaces.
