Kinetic Energy
It has potential energy.
Gravitational potential energy.
Half way down the slope, the skier has kinetic energy and potential energy. At the top of the slope, before he starts moving, he only has potential energy. At the bottom of the slope, he has only kinetic energy. This is an extremely simplified explanation, but it's probably the answer that your teacher is looking for. Hope that helps.
Potential energy. Although if the rock is pushed, moved etc. it becomes kinetic 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.
Kinetic Energy
A skier at the top has more potential energy
It has 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.
Potential energy at the top and kinetic energy at the bottom.
Gravitational potential energy.
kinetic energy
I'm guessing when their at the top of a mountain when their about to start going down, sorry i couldn't give you a better answer.
At the top of the hill, the skier possesses potential energy. As he travels down the hill, his potential energy is converted into his kinetic energy. Conservation of energy says that the skiers potential energy equals his kinetic energy further downslope (plus a little lost to heat from friction).
