Consider the following examples, which involve energy being transformed from one kind to another. Identify the initial input & final output forms of the energy in each case. Identifying intermediate energy conversions may help you in thinking about the examples, but you don't have to list all of them. For example: Water flowing over a dam and turning a water wheel. The initial form of energy is gravitational potential energy of the water in the reservoir behind the dam. The final form of energy is the kinetic energy of the rotating wheel or, if the wheel is connected to an electric generator, electrical energy. Using the previous example as a guide, identify the energy transformations in the following cases: (a) Wind driving a turbine; (b) Water heated in a microwave oven; (c) A battery operated flashlight.
