Entrance Task Answers
As the mass of the skateboarder gets higher, the amount of potential energy increases. This happens even more when the ramp is steeper.
When the skateboarder is at the top of the ramp, he has the most potential energy. As the skateboarder moves down the ramp, the potential energy changes into kinetic energy, as the potential energy is stored so the skateboarder can move. Therefore, the relationship between KE and PE is that PE changes into KE when the object starts moving.
