Define Energy

[Todd]

Energy is catigorized within 5-7 different types, although don't bother me with spelling. However, I believe I'm missing some:

Mechanical
Chemical
Heat
Radiant (Light)
Electric
Sound
Nuclear

I believe Solar is catigorized as its own type, although it may be put with Radiant.

The "Law of Conservation" states that energy cannot be created nor distroyed. This is excluding Nuclear, by spliting atoms, and explosion is made, thus light energy, heat enery, and sound energy is created. Other then that, it can only be easily be converted into a different form.

For example:

The sun gives off Solar energy, the plants absorb it and convert in into chemical energy to grow and live, although, an animal comes by and eats it, converting it into another form of chemical energy. Man slaughters the animal and converts it into ANOTHER form of chemical energy, by eatting it. Then, its converted into mechanical energy by being used to work our muscules to complete tasks.

Or:


-Turn a Knob (Mechanical Energy) on a generator
-(Electric Energy) The generator then converts the energy into light energy in a light bulb
-The light bulb lights up (Radiant)

Electric-The flow of electrons
Mechanical-Physical Movement
Chemical-Chemically altering
Radiant-Gives off light
Nuclear-Small explosion of energy made by spliting atoms
Heat-High tempitures
Solar-Light Energy given off by the sun

The movement of particals and speed of them is determined by the tempiture of which an object is undergoing. And how solid an object is. That explains why and how and object melts, or forms more solidly when hot/cold.

I could go on and on babbling as I wait for server maintenence on BB is over, cause I have no life, but lunch is ready. Later. =x


EDIT: Work, in the scientific strict definition, is moving an object from one place to another. Lift a box is work. Hold even 1,000,000 pounds, but JUST holding it, is not doing work. Pushing a car but not getting anywhere is not doing work. But yes, its true that energy is the ability to do work.

EDIT EDIT: I'd forgotten to mention, the force opposing energy and motion is friction. It creates heat and un-used energy. That is why perpetual energy/motion control is immpossible. This supports Newtons laws and theorys.
