Because on the molecular level, they are not smooth No surface is perfectly smooth and even if it were, many molecules of the two surfaces would get close enough together to interact.
What else can I help you with?
Why does some friction occur with seemingly smoth surfaces?
Some friction will occur with seemingly smooth surfaces because at a molecular level, nothing is smooth.
Why does some friction occur with a seemingly smooth surface?
I don't know... but everyone my heart is broken by a guy I like
Why does some friction occur with seeminly smooth surface?
Even though the surface appears smooth.at the microscopic level the surface has some peaks and cracks .when it slides over any other surface friction occurs. the seemingly smooth surface has some friction.
Why some friction occur with seemingly smooth surface?
Even seemingly smooth surfaces have microscopic imperfections that make contact points rough at a very small scale. When these contact points slide against each other, the imperfections create friction and resistance, even though the surface appears smooth at a larger scale.
Why does some friction occur on smooth surfaces?
Some friction will occur on smooth surfaces because even the smoothest of surfaces isn't completely smooth. There are bumps and cracks on the face of the surface when "zooming in" to a microscopic level.
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...
What does friction do with smooth surfaces?
Friction on smooth surfaces reduces the amount of sliding or slipping that can occur between the surfaces. This helps to create more resistance to movement and helps objects remain in place. However, the amount of friction on smooth surfaces is typically lower compared to rough surfaces.
Does friction acts only on rough surfaces?
no friction applies to all contacting stuffs; air, water, glass, buttcracks. No, friction can be found when two objects of mass touch. Friction can occur between two solid objects, two liquids, and even two gases. It can occur on an global scale, as well as a molecular one. Friction is simply defined as "the resistance that one surface or object encounters when moving over another."
Why is friction least effected by smooth surfaces?
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
Can Friction occur in a vacuum?
Yes, in general friction can occur in a vacuum, but the only kind of friction that doesn't occur in a vacuum is, of course, air friction. There is no drag force on an object falling in a vacuum.
Why does lubrication increase friction?
Lubrication does not increase friction; it actually reduces friction between moving surfaces by creating a barrier that allows them to slide past each other more easily. The lubricant helps to smooth out any imperfections on the surfaces, reducing the resistance and wear that can occur from direct metal-to-metal contact.
When does rolling friction occur?
i dnt no
