Fundamental forces Definition and 73 Threads

I'm just trying to get a few things straight as I delve into the world of quantum physics and string theory. First of all, what does it mean when someone says two forces combine, such as the electromagnetic and weak force as the electroweak force? Does that mean that the particles are the same...

Does all energy storage occur in fundamental forces or bonds? I believe that a rubber band stores energy in the electrical bonds between the molecules. Same with a spring. In the atom, energy is stored and released from the electrical bonds between electrons and the nucleus during photon...

Hello, I am thinking of applying for the above course and just trying to gauge how difficult it is really. I have a 2:1 in physics from Cambridge, and although at times I felt like I was knocking my head against a brick wall overall I think I might have pulled to a first if the exams had...

I read a short high-level article about the pilot wave interpretation of quantum mechanics and I have some questions. Is there a good way to formulate that theory so that the only force on a particle is from the pilot wave (inertia, gravity, EM, ... move/effect the wave which in turn...

Homework Statement interested in getting reliable information on the actual strength of the fundamental forces,including the strong nuclear, weak nuclear, electromagnetic and gravitational forces.What is their relative strengths one to another? Homework Equations The Attempt at a...

So there is a theory out there that seems to model the "four" fundamental forces based upon a higgs-like particle, which the author calls k-particles. He seems to believe that these particles act upon electrons, protons, fermions, etc. to produce forces by the means of k-particle density. It's...

I'm assuming the standard reductionist viewpoint: that chemistry is simplified quantum physics. Of the four fundamental forces in modern physics, what forces play a role in chemical reactions? Is it safe to assume it's solely electromagnetics?

What is the unit of 'strength' of the fundamental forces? When it is said that gravitational force is weaker than the strong nuclear force, how are they compared? What is meant when it is said that the fundamental forces approach each other in strength at higher energies in the early universe?

gravity: Fg = GM1M2/r^2 electro-magnetic: weak force: strong force:

I'm an Electronic and communication Engineer, and I'm living in the Caribbean, and i want to study MSc in Quantum Fields and Fundamental Forces Imperial College London, since in its description seems very likely what I'm looking for, which is,... I'm looking a course that can place me in...

We used to think gravity and electromagnetism were the two fundamental forces of nature until we discovered the strong and weak nuclear forces. Can we be wrong again and discover more forces. If not, then how are we so sure?

Could some one help me understand the difference and the similarties between Coulombic fundamental force and Gravitational fundamental force?

IDK if my understanding is right...but as far as I understand physics...all the fundament forces shares 2 characteristics - attraction and repulsion...now, here are my questions.. 1. Assume there are only 2 uncharged atoms in the universe...would they come together or go apart or stay where...

Hi all In Paul Tipler's book on modern physics (with Ralph LLewelyn) I read an explanation for the formation and stability of a molecule, which is based on Pauli's exclusion principle. This principle was responsible for a term in the energy equation, which yields also (naturally) a term in...

I have a question regarding past thoughts on the fundamental forces of nature. 1) Prior to the unification of the EM force, how many fundamental forces were there thought to be? 2) When did the concept of a force first come to be? 3) How were forces described prior to this time? Where...

Yeah, same as above, Why do fundamental physical forces change their strength with distance? Shouldn't the force be the same everywhere? Why or Why not? :-p (how do you know, and what did you get the answer from) Thanks,

If we listed all Fundamental Forces that make up Earth's Gravity, What percentage would Electro/Magnetism fall under for its influence within Gravity, I assume it would be a (minimal) of around 75% percent of the Gravity we experience, If we have all the other percentages for the other remaining...

so could anyone tell me was is weak nuclear force and electromagnism force and storng nuclear forces thank you!

hey, I am a bit confused about the forces. if there's four of them, where does color fit in? the hyper-physics website says that the strong force is a 'residual color fource'... but see the thing is, it also says the force-carrying boson is the pion, while the gluon carries the color force...

I wonder how do you distinguish the fundamental forces? After all, they are each only a bunch of Newtons.

Is it known for sure that any or all of the fundamental forces produce a push or a pull affect? Thanks.

Are we being very naive to think that there are only four fundamental forces in the universe? I mean after all the Greeks thought that there were only four elements in the universe. How do we expect to know for sure that unification involves only those four forces?

In my textbk, it says that The four fundamental forces are : a) Gravitational force b) Electric and magnetic forces c) Weak force responsible for beta decay d) Strong force which holds the nucleus together What does (c) mean? I've heard that scientists think the 4 forces were...
