cos ther are holes and cracks which contain air in them
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.
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.
True. Rough surfaces have more irregularities and bumps that create greater resistance against motion, leading to higher levels of friction compared to smooth surfaces.
True. Rough surfaces have more irregularities and asperities that create more contact points with another surface, resulting in higher friction compared to smooth surfaces.
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.

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.
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
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!
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.
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.
