low
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.
No, sand does not reduce friction but increase friction.
sand have low specific heat capacity.
it is low friction i think
Friction is high on a carpet.

Hockey. Low friction when the player is gliding down the ice. High friction when he is propelling himself down the ice.
