Energy can be classified as either stored (potential) energy and working (kinetic) energy.\nPotential Energy = the energy that an object has as the result of its position or state.\nKinetic Energy = the energy that appears in the form of an object’s motion. KE = 1/2mv2

Basically, energy is conserved in a system; it is always the same.   Heat, volume, and pressure (volume/pressure = work) can all change and you can still maintain the same internal energy of the system.  A state function is a property of a system that depends only on the current state of the system, not on the way in which the system got to that state, therefore energy is a state function.  Heat and work are not because they simply describe the way in which the system REACHED equilibrium, not the system AT equilibrium

It appears to be in relation to energy production.  I have referenced a hyperlink to a PDF file that refers to this term with in its context...the file does have some English translation.

Definitions of potential energy on the Web:\n\n    * The energy stored in a raised object (eg the weights in a grandfather clock). Potential energy equals mgh, where m is mass, g is the acceleration of gravity, and h is the vertical distance from a reference location. It is called potential energy because the energy can be regained when the object is lowered. This type of potential energy is sometimes called gravitational potential energy in order to distinguish it from elastic potential energy: see elastic energy.\n      http://urban.arch.virginia.edu/~km6e/references/glossary/struc-glossary.html\n\n    * energy stored in an object due to its position\n      http://whyfiles.larc.nasa.gov/text/kids/Problem_Board/problems/pulleys/glossary.html\n\n    * The energy which a body possesses as a consequence of it's position in the field of gravity, the work required to bring the body up against gravity from a standard level.\n      http://cimss.ssec.wisc.edu/oakfield/keyterms.htm\n\n    * Energy related to the position or height above a place to which fluid could possibly flow.\n      http://www.flw.com/define_p.htm\n\n    * The energy that matter has because of its position or because of the arrangement of atoms or parts.\n      http://www.nmlites.org/standards/science/glossary_4.htm\n\n    * Potential energy is the energy possessed by an object because of its height above the ground. The amount of potential energy possessed by an object depends on its mass and its height. A roller coaster car is initially hauled by a motor and chain system to the top of a tall hill, giving it a large quantity of potential energy.\n      http://www.learner.org/exhibits/parkphysics/glossary.html

atomic energy refers to the energy which is stored in an atom of any element while nuclear energy refers to the energy stored in the nucleus of an atom of an element. thus we can say tat both these r same since the energy of an atom is ultimately derived from its nucleus.\nthese enrgies r much useful in generating cheaper electricity. also this is the same energy thru which energy is generated in THE SUN whic is the ultimate source of all energies.

Energy stored in a body (such as a spring) whose particles have been displaced from their equilibrium positions.

energy is the capacity that an object has for performing work.  Work is a force times a distance.  A similar comparison might be your bank account balance and dollars.  While both are related and have the same units, your bank account is the capacity that you have to spend money.  The big difference is of course, you can never have a negative balance on the amount of energy in a system.

Energy comes in many forms, right? Electrical, kinetic, potential, heat, chemical etc. And energy can be converted between these forms right? i.e. when you drop something from a height, potential energy is converted into kinetic energy. Same thing when you release a compressed spring. \n\nThe quality of energy refers to the ease with which you can harness it for use and conversion to other forms. For example the energy stored in a battery is high quality energy, since it's easy to harness for use. The ambient heat energy in a room, on the otherhand, is low quality energy, since it not easy or practical to extract the energy for use.

Potential energy is the energy by virtue of its position.\nAny object which is far away from the center ofpossessingf nothing prevents it will move towards the center of earth. A spring wound fully  or partially. If left alone and it will rewind to its normal position.A  vessel containing gas under high pressure.If there is a vent the pressure will drop to normal.A string under tension. All thesrelievedamples of potential energy. These energies will be releived from the object when  there is proper way. \n\nKinetic energy is the energy by virtue of its motion. Any object moving in other words having velocity is possesing kinetic energy.If the velocity is reduced by some external agency the latter gets energy and viceversa.

Cf: atomic bombs and nuclear power plants. They use the conversion of a tiny amount of mass to lots and lots of energy.

Well, 1st thing, how much energy you want to put into it?

Delta E is a term used to describe change in internal energy which is the sum total of the kinetic and potential energies of the constituent particles.Internal energy can be changed only by allowing heat to move in/out of the system or by work done on/by the system.It is often defined as the heat absorbed at constant volume. Heat change at constant pressure is what we call change in enthalpy or delta H.

Potential energy is the sum total of all the energy that CAN BE derived.  Think of it as stored energy waiting to be released.\n\nKinetic energy is the total energy being derived at some instant in time. Unlike potential energy, kinetic energy is determined by mass AND velocity.

The human machine has three major sources of input energy: carbohydrates (bread, grains and simples sugars such as those in milk and fruit), protein (meat, legumes) and fats (too many kinds to name). When the body consumes one of these energy sources, the food molecules are broken down into smaller pieces using enzymes--doing so releases the stored energy in the food and provides small pieces from which to build more complex molecules. \n\nEach food source has a specific role to play in metabolism. Carbohydrates are the dietary source of an important sugar called glucose. In fact, carbohydrates, such as the starch in potatoes, are simply very long chains of connected glucose molecules. Glucose is so important because it is the only source of fuel for the brain, red blood cells and several other tissues. Your brain uses about 120 grams of glucose per day. Any carbohydrate consumed in excess of what is needed for running the body's basic metabolic processes is converted to glycogen or fat for long term storage.
