It's because of kinetic energy
kinetic energy
the height of the skier.
Gravitational potential energy.
Kinetic Energy
because the skis are on the snow it causes friction which turns in to heat causing the skier to stop
kinetic energy
potential energy
When skier is at the top of mountain he had kinetic energy which is further converted in to potential energy from the time when he start skiing from the top of the mountain.
skier
A skier at the top has more potential energy
Just standing there, a skier on the top of the mountain has potential energy. If she uses her poles to push-pull before taking off, she's building up a small amount of kinetic energy. If a skier is then moving down the mountain, his movement downward is kinetic energy which increases as his speed increases. If he or she collides with an immovable object while skiing, kinetic energy abruptly ends. If he or she takes off from the top of the mountain and an avalanche happens to hit at the same time, the kinetic energy of the avalanche engulfs the skier and overpowers the lower kinetic energy of the skier. The skier and avalanche become as if one in the kinetic force of the avalanche--until the skier collides with something or is buried, and thus is separated from the avalanche's kinetic energy which continues until the avalanche stops.

She is an American women skier who has won many races Some consider she is the best American skier ever
because it is peaceful and nobody can disturb them
