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.
A skier at the top of a hill would have potential energy due to their elevated position. This potential energy can be converted into kinetic energy as the skier moves downhill.
A skier at the top of a hill would have more potential energy due to their elevated position compared to a skier at the bottom of the hill. This potential energy can be converted into kinetic energy as the skier descends the hill.
A skier at the top of a hill has potential energy, which is the energy stored in an object due to its position or state. This potential energy can be converted into kinetic energy as the skier begins to move down the hill.
Electric energy is traveling to a toaster through a power cord connected to an electrical outlet. This electrical energy is then converted into heat energy within the toaster, which allows it to toast bread.
A hydropower reservoir is an example of gravitational potential energy, where the stored water has the potential to produce electricity when it flows downhill through a turbine.

A bicyclist riding downhill has kinetic energy, which is the energy associated with motion. As the cyclist descends, the potential energy from being at a higher elevation is converted to kinetic energy due to the increased speed of the bicycle.

There are two basic types of skiing - downhill, and cross country, also known as Nordic skiing. Downhill skiing relies on gravity. The skier starts from a high point and skis to a lower point. It is very difficult to progress on a flat surface or, even worth, go up hill. Skiers can achieve very high speeds, as fast as 70 KPH and more. Downhill skis are wide, the boots are very stiff and hold the leg motionless, and the bindings bind the boots to the skis rigidly. In order to go downhill, one needs to get to a high point, which means that the skier needs to take a ski lift (usually) or a helicopter (if you are very rich). Cross country skiing relies on the skier's muscle power. Most cross country skiing is done on fairly flat surfaces, with a few mild ups and downs. The skies are usually narrow, the boots flexible and the binding allows the skier to lift his heal up from the ski. Cross country ski is a quieter sport, and one of its big advantages is that it can be done anywhere there is snow, including secluded nature spots.
Gravity but the snow provides friction
Kinetic energy is given by 1/2 M x V2, that is one half mass x velocity squared
There is no other kind with a portable source of energy. Unless they had a tremendously long drop cord anyway. Wind power is not viable. Nuclear is too large and heavy. Steam is not a source of energy, it is just a manifestation of change in the state of energy. Rolling downhill also has its problems in the end.
