An Ice skater skating on ice.
One example of a material with a low coefficient of friction is polytetrafluoroethylene (PTFE), commonly known by the brand name Teflon. PTFE is a synthetic fluoropolymer that exhibits excellent non-stick properties and is widely used in applications where reduced friction is desirable, such as in cookware and as a lubricant.
Ice on ice has a low coefficient of friction, making it easier for objects to slide across its surface with minimal resistance.
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.
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.
Friction is the static electricity of two things that are rubbed against each other. Ice would have a low coefficient of friction, as things could easily slide across it. This would also make sense for something like marble, which is very smooth.
Ice skating is because you dont go fast and there is rarely any friction
human joints are an excellent example. they have a static friction coefficient of .01 μs and a kinectic friction coefficient of .003 μkanother good example would be waxed wood on dry snow (as in a snowboard on a ski slope) this has a static friction coefficient of .04 μsHope this helped!

it is low friction i think

low friction

Friction is high on a carpet.
Low friction is made when you rub smooth surfaces together, and they slide easily. For example, a melting ice cube would easily slide across a glass table because there is low friction. In contrast, high friction is when there is high resisting force. For example, if you rub velcro across a rug, there would be high friction, and it would be more difficult than sliding the ice across the glass table.
