You need a little friction when you are going down a water slide and much more
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.
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.
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.
An air hockey table with the air turned on has almost no friction. Other than that, very smooth surfaces cause very little friction. If you use certain types of cleaner on hardwood floor, it can be turned into a surface with little or no friction (and you will fall an hurt yourself a lot. not suggested.)
An example of negative friction is when a sled on a perfectly icy slope has too little friction to slow it down, causing it to slide uncontrollably at high speeds.
Ice has little friction. Sandpaper has lots of friction.

heat is really half of friction
In the bearings, where you want as little friction as possible.
Ice and marble floor have little friction and results in objects slidding as they go across the surface.
yes! you need friction for lacrosse so you don't fall
On her feet and hands. That is why they build climbing shoes from sticky rubber. Her belay partner will need friction in their belay device (ATC OR GRI GRI, etc)
than what?
You need a wooden floor and clothes that have little friction together so you could do moves like mummies. You might also need strong muscles for windmills and flares.
