Between the undersides of the skis and the snow, and between the air and your body.
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
because you need to slide down the hill....?
Most skiers wax their skis for this purpose.
Gravity but the snow provides friction
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.
It reduces friction between the bottom of the ski and the top of the snow.
Friction, Gravity, Air drag (resintince)
Friction is important for all sports.Without it it becomes really hard to accelerate or deaccelerate.For example a 100m sprinter.It would be great for him if there wasnt any air resistance (as long as he can breath).But he needs friction on the floor to push himself forward.however friction is less useful in hockey, skiing, and almost all types of boarding(snowboarding, wakeboarding, kneeboarding, sandboarding).
