Yes it is smooth
To make a wooden surface smooth, you can use tools like a sandpaper, sanding block, sanding sponge, or an electric sander. Start with a coarse grit to remove imperfections and finish with a finer grit for a smooth finish. Remember to sand in the direction of the wood grain for best results.
A rough surface with a lot of friction, like sandpaper or a rubber surface, would create the largest frictional force to resist the motion of a wooden block. Smooth surfaces have less friction and would not resist the motion as much.
This is because the surface is more even and equal. For example if you have a wooden surface and a glass surface, the wooden surface would have more friction than the glass, because it is more un-even than the glass surface
A traditional blackboard is typically made of a smooth sheet of slate or a chalkboard paint-coated surface attached to a wooden frame. Slate blackboards are known for their durability and smooth writing surface, while chalkboard paint-coated surfaces allow for easy customization on various materials such as wood or metal.
A basketball will roll faster on a smooth surface due to less friction compared to a rough surface. The rough surface creates more resistance, slowing down the ball's movement.
No, you don't, you just need a flat smooth surface.

The number of coats of polyurethane needed for a desired finish on a wooden surface depends on the type of polyurethane and the condition of the wood. In general, 2-3 coats are recommended for a smooth and durable finish.
To properly apply polyurethane to a wooden surface for a durable and protective finish, follow these steps: Sand the wood surface to remove any imperfections and create a smooth surface. Clean the surface to remove any dust or debris. Apply a coat of polyurethane using a high-quality brush or applicator, following the wood grain. Allow the first coat to dry completely before lightly sanding with fine-grit sandpaper. Apply additional coats of polyurethane, sanding between each coat for a smooth finish. Allow the final coat to dry completely before using the wooden surface.

Smooth surface
To properly prepare a wooden surface for a smooth finish between coats of polyurethane, you can use steel wool or sandpaper to lightly sand the surface. This helps to remove any imperfections or rough spots, allowing for a smoother and more even application of the polyurethane. Be sure to clean the surface thoroughly after sanding to remove any dust or debris before applying the next coat of polyurethane.
A smoothing plane is used to level or smooth rough wooden surfaces. Function is variable; however, it was designed to be used with wood. It can be used, for example, to smooth and level a rough-cut surface; or to consistently remove thicknesses from the exterior of a piece of wood. It is much more efficient than beginning to smooth a surface with extra-coarse sandpaper.
No it does not have to be smooth.
The rough surface is better than the smooth surface for the frictional force to act.
