I assume you are looking for examples. Low friction: drawer-slides, door-hinges, water flowing through the pipes. High friction: carpet pile, some types of window catch so the casement stays where set.
You can change friction by the material. e.g ice, low friction. carpet high friction.Or you could add a lubricant :D
Water can make a flat surface more slippery, which will decrease the amount of friction
low
High friction is helpful for traction. For example getting a vehicle moving, making sure it turns on curves, and stopping. Sanding might be another use of high friction. Low friction is helpful for many other things. For example, back to the car, wheels must turn easily, engine parts must turn. Everything runs better and uses less fuel with low friction. Bearings help with lowering the friction. Moving a heavy container from one side of the room to another might be benefited by low friction. You could either slide it... or perhaps pick it up with a low friction handtruck. Ice skating? As we make things move faster, even the friction of air becomes significant. So people choose aerodynamic (or low friction) shapes.
it is low friction i think
Boats usually have low friction (drag) compared to freight trains, but they have considerably more drag than most aircraft, especially the really fast ones. The faster the boat or aircraft, the lower the friction.
Friction is very useful but it has its own disadvantages. Friction causes wear and tear. Friction spoils the soles of our shoes. friction reduces speed This is all wrong some not useful types of friction are are when airplanes fly the friction causes heat that materials that will withstand which are costly.

because you need to slide down the hill....?
Friction is high on a carpet.
