"When Ayse winds up her clockwork mouse, she gives power to it. While the clockwork mouse is moving, its energy is reduced with friction; it has no power when it stops" (from student 106)
"spring has kinetic energy when it is compressed" (from student 22)
"Skier has potential energy as long as he does not move" (an example from student 72)
"A clockwork mouse has potential energy when it is not moving. Potential energy is transferred into kinetic energy when it moves. That is, it consumes more energy and it has only potential energy when it stops." (an example from student 93)
"A clockwork mouse has state energy while motionless. After it stops moving, and while it is motionless, it still has state energy. When Ayse winds up the mouse, it has got potential energy. When the potential energy is consumed, the potential energy of mouse is ready to turn into kinetic energy. When the mouse starts moving, kinetic energy is released and it has the highest energy in this state"
"Before Ayse winds up the clockwork mouse it has no energy. While winding up the clockwork mouse, some of Ayse’s energy passes through the clockwork mouse" (an example from student 48)
"Murat will lose velocity while skiing down from hill A and climbing up hill B. He will start climbing up at hill C with the help of gained velocity while skiing down at hill B. But, his speed will be zero before he comes to summit C due to gravity and he will start skiing back. He will ski reversely, with gained velocity at hill C, but he will be unable to reach the summit of hill B since his velocity again comes to zero." (an example from student 12)
"When there is no friction, the skier does not move, because there must be a frictional force between the ski and snow in order to push the ski". (an example from student 108)"The skier has to stop after a while due to lack of friction, because speed increases only in case of frictional effect" (an example from student 84)
"If there was a friction between ski and snow, the skier could climb over the hill" (an example from student 81)
