Complexity Posted January 20, 2020 Posted January 20, 2020 (edited) In my hand I have a 7.5v battery off a RC car that I've been attaching to a fan in a test of aerodynamics . The thought occurred that the battery in my hand retains a charge and the charge retains for a lengthy period . Now when I attach the fan connection and my blades start to revolve , I considered that there is now a current flowing from my battery to the fan , A to B Can you please tell me what force the fan is applying on my battery that creates an inflow of energy , extracting the energy from my battery ? F(X) = ? F is force X is vector a = charge b=wire and fan Edited January 20, 2020 by Complexity

So the answer is: none. The only force is that coming from the potential difference between the two poles of the battery. I saw your postings in some other threads. Your understanding of physics is so bad, that you cannot even ask the correct questions. Please, read some introductory physics books, get a course in physics, but stop asking stupid questions. I would propose that nobody here answers your questions anymore, unless they are questions that arise from you reading a physics book, or following a physics course. But questions that arise out of the conflict between your world view, and not accepting the answers because these do not fit your world view, is simply a waste of time for us all, including yourself.

The only force is that coming from the potential difference between the two poles of the battery. So the answer is not none then because you state there is a force and it is the force between the two poles . I assume you mean the + and - signs . So in essence you are saying a circuit is made ! Ok , can you tell me why a battery will go flat over a period of time when not being used ? Where does the charge go and by what force ?

I would say it is the other way round: the voltage of the battery could be considered (rather inaccurately) as a force that pushes electrons (from the negative terminal) and pulls electrons (to the positive terminal) hence generating a current. The current flows through the motor: some of the energy of the current is converted to kinetic energy of the fan (and the air it moves), some is converted to heat. I would caution you against trying to interpret absolutely everything in terms of force though. Not everything is caused by forces. (In GR, gravity is not a force, for example.) And, once again, your "mathematics" is a meaningless collection of symbols.

And, once again, your "mathematics" is a meaningless collection of symbols. You may be correct about my math but I really do understand the nature of forces and the physical aspects involved . Mass curves space-time energy towards it with a linear force of gravity . I disagree , force is everything more or less . The tensor force that is expanding our universe is slightly stronger than the tensor force that holds it together . A tensor force creates linear field lines and mass gravitational force curves these lines to create space-time curvature . Consider a taught bed sheet that was being supported in each corner , then drop an iron ball in the middle of the sheet so the sheet become slightly concave and curved downwards . The force that creates the curve is the gravity linear force pulling down on the iron ball . If there were no gravity ''under the sheet'' , the sheet wouldn't concave as the iron ball would have no weight to cause effect on the form of the taught sheet . P.s People don't want to try and understand my math . Any ''negative'' point of space has gravitational force . Edited January 20, 2020 by Complexity

You say you understand and then write nonsense like that second sentence, which demonstrates very clearly that you do not understand. Until you can get past this attitude of believing you understand things when you clearly don't, you will not be able to learn and get to understand the things you currently don't understand. 58 minutes ago, Complexity said: The tensor force that is expanding our universe is slightly stronger than the tensor force that holds it together . There is no such thing as a "tensor force". There is no force causing the expansion of the universe.

No. No. No. This is completely and utterly wrong.

I could never hope to win an argument against moderators but all the same I'll attempt it ! Who says there is no tensor force ? Don't you mean that nobody as yet discovered or written a scientific paper on a tensor force ? Gravity is quite clearly a force , the force that keeps things on the ground . My math means nothing to you is the correct statement , the reason is because you don't understand it and are not willing to attempt to understand it . An equivalent to aliens visiting the earth and you telling them their math is meaningless just because you personally don't get it . Likewise I see some of your math seems meaningless . My math on force etc is based on negative energy -E Where all +E is attracted to -E Consider a 4 dimensional manifold X,Y,Z and E Consider at the center of the manifold is a single point -E How would you describe in math the +E of the manifold volume being attracted to the single -E point in a centripetal isotropic manner ? Linear algebra ? I have so far : -Ec^3 Edited January 20, 2020 by Complexity

As you are the one claiming such a thing exists, the burden is on you to provide a reference that supports this.

studiot Posted January 20, 2020 Posted January 20, 2020 (edited) Actually I blame (at least partly) the current vogue to reduce the Maths to things like this [math]{G_{\alpha \beta }} = {T_{\alpha \beta }}[/math] (Baez on GR) [math]H\left( \psi \right) = E\left( \psi \right)[/math] (Hamiltonian formulation of Schroedinger equation) Those who have truly studied this stuff know that this is very shorthand hiding a multiplicity of equations and other stuff you would need to perform any actual calculations. But it leads others to think you can just write energy = whatever. Edited January 20, 2020 by studiot

In my present model that would read E=-E+E/R^3 =0 Which explains everything that exists . Edited January 20, 2020 by Complexity

It's clear you don't understand science in the least if you can say this. Eliminating subjective influences, like making up your own physics, is one of the reasons scientific methodology is so successful. Your posts violate our rules against soapboxing (because you NEVER support your non-mainstream ideas with actual evidence), and your seeming immunity to reason makes you look like a troll. I invite you to either get help by asking questions rather than pushing your misunderstandings so assertively, or just back off and try to read and learn rather than post. Unless you change your style or enjoy a less active role here, you'll get a couple more warnings and then we'll ban you. Discussing science in your style is meaningless for everyone, and actually hurts your understanding deeply. Thread closed.
