Oh well, looks like I lost that bet :smile: though if the half the energy is lost in charging a capacitor from another capacitor as heat (even in the theoretical scenario of zero resistance) how can an inductor prevent or reduce this loss since an inductor will probably have higher resistance...

more charge meaning the end results in the capacitors. Like in the example above. Starting with 0.12 coulombs in one capacitor and 0 in the other, then discharging the charged capacitor into the uncharged capacitor to end up with 0.16 coulombs of combined charge.

I understand, though all I really want to know is if you can end up with more charge then what you started with. Since half the energy is disipitated as heat when discharging a capacitor into another capacitor you end up with the same amount of coulombs on either side. What my friend and I are...

Thank you for your help guys, but just to clarify, is it possible to use a transformer to take a 10,000uf cap charged to 12v to end up with two caps rated at 10,000uf charged to 7 or even 8v each. Or to put it simply. Is it possible to end up with more coulombs then what you started with?

I understand what you are saying, but in his definition of gravitational force he has used the word force to describe what it is. That is similar to saying that the definition of Happiness is feeling happy. It defines itself and therefore requires no further explanation.

rewebster, now those are good questions! If you are satisfied with your knowledge then in your little world you are confident that you know what something is. If you are unsatisfied, then the opposite is true. However I stand by my original statement but perhaps we can compromise...

The key difference between these two expressions is the word Fruit and Force. Fruit can be defined but can you tell me what force is? Saying it is a force is merely describing its behavior. Like saying an apple is tasty. EDIT : and I just noticed you haven't described what gravity is as...

I have explained what an apple is. An apple is a fruit that grows on an apple tree. I understand what you are saying but you are asking the wrong questions.

Crosson, rewebster, and gear300 have put it very well. I can tell you what an apple is. An apple is a fruit that grows on an apple tree that contains seeds that can grow into other apple trees. It is biological and consists of cells. They are usually red, have a waxy skin and are very...

ok... I am going to have to stop this now. Yes I can tell you what an apple is. and, like gravity, I can tell you how it behaves. If you want to know then pm me because you are taking this thread way off topic.

Your not far off :biggrin: I'm bound to get shot for saying this on a physics forum but to quote socrates "True knowledge exists in knowing that you know nothing." See what you made me do! This is a thread about gravity and you have reduced me to a level where philosophy has had to enter...

To know something we would know the cause of gravity. We would also have a model that would work universally from macro to plank space. Perhaps a theory exists that I don't know of, but even then it will just be a theory.

lol... that wouldn't surprise me. I don't claim to be able to predict the behavior of my closest relatives... AT ALL I don't want to start an argument. I am just trying to put across that saying all you want to know is the behavior of a "thing" is like saying all you want to know is how to...

If that is all you want to know then I am envious.

I think the simplist answer is we know NOTHING about gravity. there is only theory on what gravity actually is... all we know are its effects. for example the mayans knew with amlost perfect accuracy about the suns behavior to such a degree that they could predict the Earth's presession...
