Energy Transformation

Energy Transformation

Energy transformation is the process of changing energy from one form to another. This process is happening all the time, both in the world and within people. When people consume food, the body utilizes the chemical energy in the bonds of the food and transforms it into mechanical energy, a new form of chemical energy, or thermal energy. Energy transformation is an important concept in the application of the physical sciences. The ability for energy to be transformed automates, lights, entertains, and warms the world in an astounding multitude of ways.
The concept of energy transformation can be illustrated in a number of common activities. An engine, such as the engine in a car, converts the chemical energy of gas and oxygen into the mechanical energy of engine movement. A light bulb changes the chemical energy of the bulb into electromagnetic radiation, or light. Windmills harness the energy of the wind and convert it into mechanical energy in the movement of the turbine blades, which is then converted to electrical energy. Solar panels transform light to electricity.
Energy can be transformed from one kind to another, but that process occurs primarily at the quantum level. Energetics is the scientific study of energy under movement and storage under transformation. Energy moves at all scales, from the quantum, which is essential to all energy transformation and movement, to biological systems, stellar evolution and the cosmos as a whole. Principles here means a phenomenon that is invariant throughout time and that experiments done by different people at different times with the same procedure produce the same results. When enough people have achieved the same results, the observation of the principle then becomes afundamental law. Fundamental laws are what theories are based on and until something can become established as a working theory, it is a hypothesis. Such a law of energy transformation exists as determined by Einstein and...
