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
The needle was floated in water in the first crude compass to reduce friction and allow it to move freely in response to Earth's magnetic field. This helped the needle align itself with the Earth's magnetic north and south poles, indicating direction.

low friction
A compass must be floated on water to ensure it can pivot freely and accurately align itself with the Earth's magnetic field. When placed on a stable surface, external forces and friction may prevent the needle from moving freely, leading to inaccurate readings. Floating on water minimizes these influences, allowing the compass to respond naturally to magnetic north. This is especially important in navigation where precision is crucial.
The thing that helps the needle move freely in a compass is called a pivot or bearing. It is usually a low-friction point that allows the needle to align with the Earth's magnetic field and point north.
Friction is high on a carpet.
low
Smooth surfaces, lubricants, and reducing the contact area between two objects are factors that can cause low friction. Additionally, using materials with low coefficients of friction such as Teflon can also help reduce friction.
Ice skating is because you dont go fast and there is rarely any friction
Hockey. Low friction when the player is gliding down the ice. High friction when he is propelling himself down the ice.
