Connecting Newton and Coulomb: Is There a Link Between Their Laws?

In summary, the mathematical link between Newton's law of gravitation and Coulomb's law of electricity is trivial. However, a great expert like you may have original informations out of string theory, which may unite electromagnetism and gravity.

Do you know if someone already found a link between Newton : F = G mm'/r^2 and Coulomb : F = K qq'/r^2 laws ?

link? what kind of link? Please specify at what level this link "should be".

Are you asking if there is a theory of unification of electromagnetism and gravity?

The mathematical link is trivial, it is simple potential theory and differential equations.
 
  • #3
of course the mathematical link is trivial but I was thinking about the unification between electromagnetism and gravity. I know it is the famous GUT that everybody wait. But I wanted to know if a great expert like you has original informations out of string theory.
 
  • #4
no GUT is strong + electro + weak.

If you want to acquire information about string theory, we have a sub forum called "Beyond the standard model" where people are more than happy to answer your questions and put you in the right direction.

However, I encourage you to search for older threads and reading FAQ and sticky threads and the forum rules before proceeding.

you have not respond to my question, I said "out" of string theory !
 
  • #6
I can't understand everything you are posting here since your English is not "the best".

"original informations out of string theory"

Means what?? The grammar in that sentence is also wrong, sorry, but it is really hard to know what you mean.
 
  • #7
ok glenn I will try : I mean : do you know something different from string theory and able to make a physical (not mathematical) link between these laws.
 
  • #8
"something different from string theory"

do you mean

"something different THAN string theory"?

Also, the physical link will involve math of course...
 
  • #9
true, different than string theory and with all the math you want :-)
 
  • #10
why not string theory?
 
  • #11
why not ?
 
  • #12
Yes, why don't you consider String Theory as a possible TOE?
 
  • #13
I consider string theory a possible way but perhaps it is not the only way and my question is do you know another way ?
 
  • #14
well as I said, better to ask in the "beyond the standard model forum", a mentor will most probably move this thread to that place for you.
 
  • #15
ok glenn thank you for your help and I hope to exchange with you asap
 

FAQ: Connecting Newton and Coulomb: Is There a Link Between Their Laws?

How are Newton and Coulomb laws related?

Newton and Coulomb laws are both fundamental laws in physics that describe the behavior of objects. Newton's laws of motion explain the relationship between an object's mass, acceleration, and the force acting upon it, while Coulomb's law describes the force between two charged particles. Both laws involve the concept of force and can be used to understand the behavior of objects in various situations.

Can Newton's laws be applied to charged particles?

Yes, Newton's laws of motion can be applied to charged particles as they also experience forces due to their mass and acceleration. However, Coulomb's law is more accurate in describing the behavior of charged particles as it takes into account the repulsive or attractive forces between them.

How does Coulomb's law mathematically relate to Newton's laws?

Coulomb's law and Newton's laws are mathematically connected through the equation F = ma, where F represents the force acting on an object, m is the mass of the object, and a is the acceleration. In Coulomb's law, the force between two charged particles is represented by F = kQ1Q2/r^2, where k is the constant, Q1 and Q2 are the charges of the particles, and r is the distance between them. By equating these equations, we can see the relationship between the two laws.

What is the difference between Newton's laws and Coulomb's law?

The main difference between Newton's laws and Coulomb's law is the type of forces they describe. Newton's laws explain the behavior of objects with mass, while Coulomb's law explains the forces between charged particles. Additionally, Newton's laws are applicable to all objects, while Coulomb's law applies specifically to charged particles.

How do Newton and Coulomb laws contribute to our understanding of the universe?

Both Newton's laws and Coulomb's law are fundamental laws in physics that are used to understand and explain the behavior of objects in the universe. These laws have been crucial in developing our understanding of motion, forces, and interactions between objects. They have also been essential in the development of other laws and theories, such as Einstein's theory of general relativity.
