The surface that has the lowest friction is a wet surface, or a surface that has been oiled with light oil, or the air cushion underneath a hovercraft. Then there is the train that runs on magnetic rails, hovering above the rails without physically touching.

Ice has the lowest friction of common surfaces due to its smooth and slippery surface.


What is surface friction is?

Surface friction ALWAYS point parallel to the surface and opposite motion. There must be a normal force for there to be friction

How does roughness of surface that are touching affect the friction between the surface?

the rougher the surface is, the more friction there will be


How does the surface of an object affect friction?

the smoother a surface is, the less friction it produces.


When an object roll over a surface the kind of friction that occurs is called friction?

When an object rolls over a surface, the friction that occurs is called rolling friction. Rolling friction is lower than sliding friction, which occurs when an object slides along a surface. Rolling friction results from the deformation of the object and the surface it is rolling on.


What is the friction that exits between a surface sliding on another surface is called?

If the two surfaces are moving relative to each other, then the friction between them is Kinetic Friction. Prior to the surfaces moving there was Static Friction between them.

What is the force that resist the movement of one surface past another surface is called?

A force that resists motion of one surface across another surface is called FRICTION(or FRICTIONAL FORCE)


When a body slides over a surface the kinetic friction and static friction related as?

Kinetic friction is the friction that applies when an object is moving; static friction is the friction that applies when the object is not moving. Static friction must always be greater than, or equal to, kinetic friction.


Does surface type affect the force of friction?

Surface types can affect the force of friction because as the surface gets rough and rougher it has more friction and smooth surface has less friction. if we compare the affect of friction force on a ice and road. Road is much more rough than the ice chunk and if we slide a ice hockey puck on each of the surfaces, we get that smoother surfaces has less friction.


When an object rolls over a surface the kind of friction that occurs is called round friction.?

The friction that occurs when an object rolls over a surface is called rolling friction, not round friction. Rolling friction is typically less than sliding friction because the object's motion is smoother and involves less resistance from the surface.
