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.
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.
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.
The amount of friction is generally greater between rough surfaces because the irregularities on the surfaces create more points of contact and interlock, increasing resistance to motion. Smooth surfaces have less interlocking and contact points, resulting in lower friction.
Yes, rough surfaces generally have more friction than smooth surfaces because there are more points of contact between the two surfaces, leading to greater resistance when attempting to slide or move one surface over the other.
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

True.
two rough surfaces
Rough because it takes longer to slide and gets more friction
two rough 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!
Friction is greater on rough surfaces compared to smooth surfaces because there is more area of contact between the surfaces, leading to more resistance against motion. Rough surfaces have more irregularities that interlock and create obstacles to movement, hence increasing friction.
