ice skating on ice ,is one friction occurring
Sandpaper and asphalt both have relatively high coefficients of friction.
Some examples of relatively high friction surfaces are: sand paper, grass, and asphalt. In general, the rougher the surface, the more friction it has.
Friction can be very useful in your life. You need low friction when you ski. If you have high friction you cannot glide easily on the snow. You can also use low friction when you ice skate. If you have high friction you cant glide across the ice. When you use your laptop your keypad has to be able to glide. Some examples of high friction are erasing with your pencil, rubbing your hands together etc.
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.

Example of high friction is a really rough surface like sandpaper.

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.

Examples of SLIDING FRICTION is pushing a heavy rock in your path, or moving a box on the floor.
Friction is high on a carpet.
The fact that you can walk without sliding is an example of friction.
