... As the matter “falls in”, to create the sun, the potential energy is converted into other forms, and is subsequently released in the form of radiation. The sun radiates at a rate of 3.86 × 1026 W; if all this came from gravitational energy, how long would the sun last? 3. Find the average potential ...

Energy Basics
... Chemical energy is energy stored in the bonds of atoms and molecules. Batteries, biomass, petroleum, natural gas, and coal are examples of stored chemical energy. Chemical energy is converted to thermal energy when people burn wood in a fireplace or burn gasoline in a car's engine. Mechanical energy ...

Energy Exists in Many Forms
... Energy may be transformed between different forms at various efficiencies. Items that transform between these forms are called Transducers. It's good to know that energy does not disappear, it merely changes form. To receive different forms of energy we use different energy sources and technologies. ...

Conservation of energy
In physics, the law of conservation of energy states that the total energy of an isolated system remains constant—it is said to be conserved over time. Energy can be neither created nor be destroyed, but it transforms from one form to another, for instance chemical energy can be converted to kinetic energy in the explosion of a stick of dynamite.A consequence of the law of conservation of energy is that a perpetual motion machine of the first kind cannot exist. That is to say, no system without an external energy supply can deliver an unlimited amount of energy to its surroundings.
