Why are cars designed with smooth surfaces?
to reduce air resistance
An echo is most likely to result when sound hits a surface that is?
sound wave reflect best off smooth, hard surfaces
Smooth tissues that cover surfaces are?
Epithelial tissues are the smooth tissues that cover surfaces in the body. They serve as a protective barrier and are found in the skin, lining of organs, and throughout the body. Epithelial tissues are designed to absorb, secrete, and protect underlying structures.
What bony projections is smooth in order to articulate with another bone?
Articular surfaces of bones are smooth bony projections that are designed to articulate with another bone, forming a joint. These surfaces are covered with cartilage to reduce friction and allow for smooth movement. Examples include the femoral head articulating with the acetabulum in the hip joint.
What do smooth surfaces usually have less than rough surfaces?
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.
Why is there less resistance on a smooth surface?
Because friction is less on smooth surfaces. Smoother the surfaces, lesser the friction.
Why do water droplets form on smooth surfaces?
Water droplets form on smooth surfaces due to condensation. When the smooth surface is cooler than the surrounding air, the water vapor in the air comes into contact with the surface and cools down, leading to the formation of liquid water droplets. This process is more likely to occur on smooth surfaces because they provide a uniform surface for the droplets to accumulate.
Why does rough surfaces have more friction compared to smooth surfaces?

Are rough surfaces have more friction than smooth surfaces?
True.
Why is friction least effected by smooth surfaces?
Friction is least affected by smooth surfaces because there are fewer microscopic irregularities that can interlock and create resistance between the surfaces. This results in less friction compared to rough surfaces where more interlocking can occur, increasing the resistance.
Do smooth surface produce friction?
Yes, smooth surfaces can still produce friction. Friction is caused by the resistance between two surfaces when they are in contact with each other, not only by the texture of the surfaces. Smooth surfaces can still generate friction, although the amount of friction may be lower compared to rough surfaces.
Why friction does not occur in smooth surfaces?
It is wrong to say that friction doesn't occur in smooth surface.. As ideally, no such surface exists, which has 0 value of friction. We can say that the magnitude of friction force is less in smooth surfaces as compared to that in rough surfaces. Friction opposes the motion of a body. When we go to the molecular level, we can see that the surface of a plane is not smooth but rough.. We cannot see that roughness through naked eyes. But the amount of roughness differs from object to object. The so called smooth surfaces have less roughness as compared to un-smooth surfaces. Hence, the magnitude of friction is LESS in smooth surfaces...
