There are several examples of surfaces that have little friction between them. They are water against a boat, crude oil in water, ball bearings, roller bearings, and graphite.
Surfaces with very little friction include ice, polished metal surfaces, and Teflon-coated surfaces. These surfaces reduce friction because they have smooth textures or surface coatings that allow objects to slide over them with minimal resistance.
smooth surfaces
In the context of friction, "little" would typically mean that there is not much resistance or opposition between two surfaces in contact. This would result in smoother movement and less energy loss due to friction.
Friction is the force that resists motion between two surfaces in contact. In the vacuum of space, there are no surfaces or molecules to create this friction. Objects in space can move freely without friction because there is very little resistance to their motion.
The result of a small amount of friction between two surfaces could be a decrease in the speed at which one surface moves past the other, or a slight resistance when attempting to slide the surfaces against each other.

Smooth ones, especially if there's a bit of liquid involved (ice skates).

Rubbing a balloon against your hair. Sliding a book across a table. Skating on ice. Walking on a rough surface. Options 1, 2, and 4 are examples of friction as they involve surfaces rubbing against each other, creating resistance. Skating on ice, however, involves very little friction due to the minimal contact between the skate blade and the ice surface.
no substance is perfectly smooth.it has tiny bumps and bruises and when two surfaces move over each other the bumps and holes in get in each other's way.oil covers up these bumps.it also forms a layer between the two surfaces and prevents direct contact between them.there is very little direct contact between the holes and this way the friction is reduced
Styrofoam has a low coefficient of friction, meaning it is very smooth and produces little resistance when in contact with other surfaces. This low friction coefficient allows styrofoam to slide easily across surfaces.
You might need as little friction as possible in situations like lubricating machine parts to reduce wear and improve efficiency, minimizing friction between moving components in high-speed vehicles like airplanes or cars to maximize speed, or reducing friction between surfaces in medical devices to prevent tissue damage during surgery.
a little bit of movement no movement sliding around
The coefficient of friction between glass and wood can vary depending on factors such as surface finish and moisture content. However, on average, the coefficient of friction for glass on wood is around 0.4 to 0.6. This value indicates moderate to high friction between the two surfaces.
