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.
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.
True. Rough surfaces have more irregularities and asperities that create more contact points with another surface, resulting in higher friction compared to smooth 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.
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...
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.
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.
