Metal has low friction because its smooth surface allows for easier movement of objects over it. The atomic arrangement in metals allows for minimal resistance between surfaces, reducing friction. Additionally, metals can form a layer of oxide on their surface which further decreases friction between two metal surfaces.

How is it that wood has more friction on metal than felt?

Wood has a rougher and less flexible surface compared to felt, leading to greater surface contact and thus more friction with the smooth surface of metal. Felt has a smoother and softer texture, which reduces the surface area in contact with metal and therefore decreases friction.


What is the difference between friction and antifriction bearing?

Friction bearings rely on direct contact between surfaces, such as metal on metal, to support loads, while antifriction bearings use rolling elements (balls, rollers) to reduce friction and support loads more efficiently. Antifriction bearings are typically smoother, have lower friction, and require less maintenance compared to friction bearings.


Why is kinetic friction less than static friction?

Kinetic friction is typically less than static friction because the surfaces are already in motion when kinetic friction is acting, so less force is needed to overcome the resistance between the surfaces. In contrast, static friction must be overcome to initiate motion, requiring a greater force.


What are 3 types of surfaces that produce less friction?

Ice: Due to the low friction coefficient between ice and another surface, it results in less resistance to movement. Teflon: This material has low friction properties, making it commonly used in non-stick cookware. Smooth polished metal surfaces: When two smooth metal surfaces come into contact, the friction between them is minimal compared to rough surfaces.


What types of surfaces create less friction?

Smooth and flat surfaces, such as ice, glass, or polished metal, tend to create less friction compared to rough or textured surfaces. Lubricated surfaces, such as those coated with oil or grease, also reduce friction by providing a slippery layer between the moving objects.

Will a toy car go faster down a wooden or metal ramp?

If these ramps are the same gradient and length then in theory it should be the metal as its surface is smoother so there is less friction

Why do large particles in a rock layer cause less friction than small particles?

Large particles have less total surface area, so caused less friction then the smaller particles do


Which metal cannot be easily charged by friction?

Gold is a metal that cannot be easily charged by friction. Its high electrical conductivity allows charges to disperse quickly, preventing the buildup of static electricity. Unlike other materials that can become charged through friction, gold's properties make it less effective for this purpose.
