Greetings,
I am interested in learning all the different "laws" and "theories of laws" related to Physics. I do realize that I could take a class or purchase a book but however I would rather use the knowledge of the EVC forum to learn about Physics. I would like to start with "understanding gravity" to be able to apply it to other ideas such as the Big Bang model.

Thank you

Dear tthzr3,
I know there are a number of people on the boards with substantial physics knowledge but I'm not sure that a thread such as the one you propose will work as it stands.
A better approach might be to formulate a clearer question relating to the role of gravity in the big bang and from that develop a dialogue which will increase your understanding.
TTFN,
WK

Understanding Gravity 101
Thread moved here from the Proposed New Topics forum.
********************************************************************
Perhaps you could elaborate by telling us what you don't understand about gravity.

Tross,
In reading your earlier posts, I noticed that you used the bible to provide support for your assertions in a previous physics thread (Is Space Flat?).
AdminPhat has seen fit to promote this topic and has placed it in the Science Forum. That means:
Rule #4. Points should be supported with evidence and/or reasoned argumentation. Address rebuttals through the introduction of additional evidence or by enlarging upon the argument. Do not repeat previous points without further elaboration. Avoid bare assertions.
TRANSLATION:
Evidence = scientific evidence.
Evidence ≠ the bible.
Just a friendly reminder.

It is probably not a good idea to get the impression that you can "understand gravity" it just a few short lessons, much less the big bang.
However the journey of a thousand miles and all that rot leads us to begin at the beginning.
May I ask about what knowledge you do possess concerning physics?

First of all, I'm assuming that you've been through high school, so correct me if I'm wrong.
Let me ask you a few questions. Did you learn geometry by reading a few paragraphs somewhere? Did you learn algebra by reading a few paragraphs somewhere? Did you learn chemistry by reading a few paragraphs somewhere? Did you learn U.S. histry by reading a few paragraphs somewhere? Did you learn U.S. literature by reading a few paragraphs somewhere? Did you learn psychology by reading a few paragraphs somewhere?
If the answer is yes to any of these, you are way smarter than I am and therefore I will leave you on your journey.
If the answer is no to all of these, what on Earth makes you think you can learn physics, specifically gravity, by reading a few paragraphs here?
I hesitate to tell you anything about gravity on here because it's hard to go deep into mathematics of the theories on a forum and it's impossible to talk about gravity without mathematics. If I don't go deep into mathematics, you will undoubtedly nitpick at the layman's terms and then proclaim yourself to be the smartest person in the world for disproving the layman's terms of gravity.
In either case, you can't learn about gravity on an open forum like this. We could talk about specific aspects of gravity if you'd like. But I highly doubt anyone on here or anyone at all can dumb down and shrink probably several years of college courses into a few paragraphs to teach you gravity.
Again, if you want to talk about specific aspects of gravity, I'm all yours.

Owing to the deficiency of the English language, I have occasionally used the academic jargon generator to produce phrases that even I don't fully understand. The jargons are not meant to offend anyone or to insult anyone's intelligence!

Just a thought. There is no easy way to learn. May I suggest that you buy a book. It can be fascinating.
If you want a very basic book that cover a number of interesting fields I'd suggest A Short History of Nearly Everything by Bill bryson
If you want something a little more in depth but still very basic I'd suggest The Fabric of the Cosmos by Brian Greene
Both great reads. Have fun

Everybody is entitled to my opinion.

understanding physics
the true nature of physics is not largly understood.
theorys abound and i have some of my own. but physics in general is such a large topic that you would have to be a math wiz to understand even the basics of physics laws.
gravity: the mathmatical equation that was written for gravity is a window into the stars, with some research youll find that although gravity is understood mathmatically, that the equation is also faulty. einstien attempted to correct the overlooked details in the basic equation of gravity, since the equation was like a 2 d model of a 3d equation, and resulted in what you probrobly know as the theory of relativity.
my personal theory is that gravity is a collective sharing of the g-force found in atoms, since atoms collectivly retain mass and weight by the concentration of matter (atoms. gravity is the attraction of mass and on large scale, the force that controls the uniform movement of all great masses in our universe, like the cylce of the planets, the movement of the sun in the galaxy, and the movement of galaxies in the greatness of space by there vacinity to each other.
the g-force in atom and nuclear activities are a much more powerful force than gravity, but as i said before, i beleive that these two forces are one and the same, and understanding the smaller will lead to better understanding of the greater.
disclaimer: all mispellings and opinions belong to me the writer, feel free to bash meh :/

Re: understanding physics
Why Tesla.
You're absolutely right!
Amazing that none of the thousands of theoretical and experimental physicists working today stumbled on your brilliant theory!
I suggest you write it up and submit it to the appropriate journal.

Re: understanding physics
well..if you really want to give the topic poster some help, go ahead and start with the basic math for gravity and then the math for einstiens theory of relativity, and see if the initial poster got enough?
according to newtons law: (force)=inertial mass)x (acceleration),
the enertia massis a characteristic constant of the accellerated body. , if now gravitaiton is the cause of accelleration, we have
(force)=(gravitational mas)X (intensity of the gravitational field)
where thegravitational mass is likewise a characteristic constant for the body. from these two relations as follows:
.........................(gravitational mass)
(acceleration)= _____________________
..........................(inertial mass)
X (intensity of the gravitational field).
if now, as we find from experiance, the acceleration is to be independant of the nature and the condition of the body and always the same for a given gravitational field, then the ratio of the gravitational to the inertial mass must likewise be the same for all bodies. by a suitable choice of units we can thus make this ratio eaqual to unity.
we then have the following law:
the GRAVITATIONAL mass of a body is equal toits INERTIAL mass.
(from einstiens special theory of relativity part II)
hope that at least points you in the right direction mr poster, although..you might want to hit the library or take some book suggestions from above.
