Energy????

Question

What on the earth is energy? Is it only what we are taught in physics class or is it anything more?

Answer 1

Physics class is just the begining of the journey, never the destination. Energy is the ability to do work. (standard textbook definitiion). It is also the second largest financial derivative opportunity right now (behind interest rates) -- fianancial definition. It is a battleground for the next presidential election (political definition), and an excuse for not mowing the lawn (relationahip definition).



Good place to go is wikipedia...

The term Energy (from Latin Energia and Greek Ενεργεια) refers to the ability of a physical system to do mechanical work.[1] It is a fundamental concept pertaining to the ability for action. The energy of a system can be quantified in many interdependent forms, but the total energy of a system is subject to conservation.



Energy is not measured as an absolute quantity, but as relative to a reference state or level. For example, a litre of water has more thermal energy when it is warm than when it is cold, and a car in motion has more kinetic energy than when it is at rest. It is important to realize that the selection of a reference state is arbitrary and has no effect on how a physical system operates, but that an informed selection can greatly simplify one's understanding of that system.

Answer 2

its the power needed to perform any act. by anything. things, humans, animals, planets...



every thing in the palent have energy, some have very little energy and some, well, alot of energy.

energy have alot of types, and ya like you were tought in phisics class.

the only "magical" thing about energy, i think, that it never disapears, it only tranfor to diferent kind of energy.

Answer 3

enrygy is the capacity to do work. the forms of energy are the following potential and kinetic energies.

Answer 4

Well they say, if you eat a bar of chocalate your getting energy into your body.It makes sense to conclude from this scientic statement that energy must be chocolate.

Thats it! why didnt I think of that before.

Energy is Chocolate!!

Answer 5

universal definition: energy is simply the ability to do work.

Answer 6
