because you need to slide down the hill....?
you need low friction
it rubs against the snow witch causes friction
when you are jumping or making a turn
Most skiers wax their skis for this purpose.
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.
low
low friction
You need friction to slow down or turn while skiing and ice skating. Auto braking during driving. Walking or the movement of the motor vehicle depends on friction or there will not be movement.
Air resistance and friction with the snow.
if there is friction on the hill it will slow you down
it rubs against the snow witch causes friction
when you are jumping or making a turn
So the bobsled can slide...
Most skiers wax their skis for this purpose.
Gravity but the snow provides friction

it is low friction i think
Between the undersides of the skis and the snow, and between the air and your body.
