Because rough surfaces prevent the edges of the suction cup from creating a seal, which a suction cup needs to function.
Yes, suction cups can stick to wood surfaces. However, the effectiveness of the suction cup may depend on the type of wood, its finish, and how smooth the surface is. Rough or porous wood surfaces may not provide a good seal for the suction cup.
Suction cups adhere best to smooth, non-porous surfaces such as glass, tile, metal, or plastic. These surfaces provide a tight seal for the suction cup to create a vacuum and stick securely. Rough or porous surfaces may not allow for a proper seal and may cause the suction cup to lose its grip.
Yes, polyurethane can smooth out rough wood surfaces by providing a protective and smooth finish when applied correctly.
two rough surfaces
Two rough surfaces in contact will produce more heat due to increased friction compared to two smooth surfaces or a smooth and rough surface. Adding oil between two surfaces will reduce friction and heat generation.
Smooth surfaces usually have less friction than rough surfaces because there are fewer irregularities and protrusions that can create resistance when two surfaces rub against each other. This causes objects to slide more easily on smooth surfaces compared to rough surfaces.
No. How well a suction cup sticks to a surface has to do with how will a seal can be formed on the surface. Rough surfaces will not form good seals compared to smooth surfaces which means that suction cups will not stick as well to rough surfaces as they do to smooth surfaces.

True.
two rough surfaces :)
Smooth vs. Rough surfaces. Rough surfaces have more surface area than smooth surfaces. This means that there are increased incidences of molecular reactions between the surface and object
Rubber suckers may have difficulty sticking to rough surfaces due to the irregularities in the surface preventing a proper seal. A smooth surface allows for better suction by creating a vacuum when pressed against it.
