Smooth surfaces are flat and even, lacking any bumps or irregularities. They allow objects to glide easily over them, which is why materials like glass, metal, and polished wood are often considered smooth. These surfaces can be found in everyday items, such as tables, floors, and mirrors. In addition to being visually appealing, smooth surfaces can also affect how objects interact with them. For example, a smooth road provides better traction for vehicles compared to a rough one. Smooth surfaces are essential in various fields, including manufacturing and design, where precision and functionality are crucial.
