"Calories" really means "Kilocalories", because it sounds better than saying that you are on a millioncalorie diet.
Half a century ago when the world converted to the MKS (metric) system, dietary calories were never converted into Newtons, and now probably never will.
potenial energy
Another word for chemical energy is potential energy stored in chemical bonds within molecules.
I don't believe there is a special word for stored energy, I would just call it that, "stored energy". Energy of position is called potential energy. For example, if you lift a weight against the force of gravitation, the energy you transfer to the object is stored as gravitational potential energy. At a higher position, it has more of this energy than when it is at a low position.
Most foods that are perishable need to be stored in a refrigerator. Perishable foods spoil faster if they are not refrigerated.
Well, the energy might be stored in a brick sitting on a shelf and when you drop it that energy is turned into kinetic energy. When the brick hits he ground the kinetic energy might be used to break it up into pieces.
Yes, dam water is an example of potential energy because it has the potential to do work when released and flows downhill due to gravity. The stored energy in the water is converted into kinetic energy as it moves downstream.
The water at the top of a waterfall has a great amount of potential energy.
Potential
The word used to describe the amount of energy released by an earthquake is "magnitude." This is typically measured using the Richter scale or the moment magnitude scale.
Carbohydrates are broken down to release energy for the cells in the body. If an excess of energy is produced, the extra energy will be stored as fat.
If it is mechanical energy, that is called "work". For thermal energy, the word "heat" is used. For energy in general, I don't think there is a special name for it.
The word 'excess' is both an adjective and a noun.The noun 'excess' is a word for an amount that is more than the usual or necessary amount; a word for a thing.Example uses:Mother saves the excess material for quilting. (adjective)An excess of goods is stored at our warehouse. (noun)
