Question

Energy is the ability to do work. Energy comes in various forms and can be transformed from one form to another. However, the total energy will always stay the same, because energy cannot be either created or destroyed. This principle is known as the Law of Conservation of Energy. For example, the electric motor in a roller coaster uses electrical energy to drag the coaster up the hill. At the top of the hill, the electrical energy is converted into gravitational potential energy. According to the above definition of work, which person is doing the most work?
