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.
Smooth surfaces produce less friction than rough surfaces because there are fewer irregularities and obstacles for the objects to overcome when sliding past each other. The rough surfaces have more contact points between the two surfaces, creating more resistance and increasing the friction.
Rough surfaces tend to have more friction compared to smooth surfaces. This is because rough surfaces have more microscopic irregularities that create greater resistance as objects move across them. Smooth surfaces have less friction due to the reduced contact and interaction between the surfaces.
Rubbing together two smooth surfaces will typically result in less friction compared to rubbing together rough surfaces. This is because smooth surfaces have fewer irregularities and less surface area in contact, leading to reduced friction. Rough surfaces have more contact points and irregularities, increasing friction.
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
Yes. Think about two steep hills. One is covered in ice (smooth). The other is covered in sandpaper (rough). The ice covered hill would be MUCH easier to slide down. Thus, the friction is much LESS, on a SMOOTH SURFACE. Then the opposite must be true, that friction is GREATER on a ROUGH SURFACE.
Because there is less traction for an object to grab onto on a smooth surface rather than when an object runs over a rough surface.
rough surfaces because it has more bumps that stop it from moving faster

smooth surfaces have less friction, take an ice rink for example, the resistance on that is less than the resistance on asphalt

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...

Surface friction is defined as the resistance of an object experiences during motion. So, for the same object, a smooth surface has less friction than a rough surface. Think about skating on ice or a piece of plywood!
Snails move faster on rough objects as the sticky liquid they use for locomotion gets good friction and helps it to move. But on rough surfaces, the frictional force is much less and the snail can hardly move.
