Gravity and the force applied by the poles.
Friction is extremely important in that it causes heat which causes the snow to melt (a little) and the ski or sled runner actually runs on the layer of water. If there was no friction then you would not move. :) Hope this helped :)
the force that is used shall be gravity .
Work is done when force is used to be approximately constant
muscular force
Upward force, used to counter the downward force of gravity acting on the climber. Precisely the same force used when walking up a flight of stairs. Provided in both cases by the climber's muscles.
Gravity but the snow provides friction
An object in motion stays in motion with the same velocity unless acted on by an unbalance force. That is newtons 1st law. Skiing demonstrates this because you are staying in motion by resisting the force of gravity and friction, so you are the inbalance force. An ubalanced for is a force when two object pushed against each other and one wins. So there is an unbalanced for. So when you skiing your that ubalanced force which is resisting gravity and friction.
Skiing was invented in Scandinavia where they used to speak Norse, the word skiing comes from the old Norse word skíð which translates as a stick of wood
It is important to stretch well before skiing, especially the buttocks, thighs, knees, shins, and ankles. These muscles are used the most when skiing, along with the biceps.

Cross-country skiing has been used for centuries in colder climates to get from one location to another.
'Sticks' used to ski are called skiing poles.
Newton's second law deals with mass and force as it relates to acceleration. Acceleration down the hill is the main part of skiing, which skiers can affect by changing their mass or the force they use to push themselves down the hill.
It can be used that if it's a change of possion u can quickly turn around as fast as u can.
Slalom is the name given to water skiing with one ski.
