Difference between color and strong forces?

In summary: The color force is the fundamental force that binds quarks together inside of nucleons. Even though nucleons are "color neutral", there is a small amount of interaction between nuclei thanks to the color force "bleeding over" to a nearby nucleon that gives rise to the very short range strong force. This is similar to how neutral atoms can be still be attracted to each other at close range."

can anyone explain me about the differences between color and strong force?Though there are four fundamental forces so from where does the color force come?

If I am not mistaken, quarks are held together by gluons and like quarks have up, down, charm, strange, top and bottom with their anti quark partners, gluons are called red, green and ( forgot one more color) and my the exchange of gluons, the quark remain together. In fact, the carriers of strong force are gluons and they carry color charge.
In short, just like the photons are the carriers of EM force, gluons are the gauge bosons of strong force and they keep the quarks intact.
Its better if you look at wikipedia and do some research on QCD.

"Color force" is another name for the strong force.

But after posting this question I searched more articles and found the following extract saying

"Since quarks make up the baryons, and the strong interaction takes place between baryons, you could say that the color force is the source of the strong interaction, or that the strong interaction is like a residual color force which extends beyond the proton or neutron to bind them together in a nucleus."

The color force is the fundamental force. It holds quarks together inside of nucleons. Even though nucleons are "color neutral", there is a small amount of interaction between nuclei thanks to the color force "bleeding over" to a nearby nucleon that gives rise to the very short range strong force. This is similar to how neutral atoms can be still be attracted to each other at close range.

Perhaps a better term would be to call the interaction between nuclei the "nuclear force" and just use the strong force and color force interchangeably.

1. What is the difference between color and strong forces?

The color force and the strong force are both fundamental interactions that play a crucial role in the behavior of particles at the subatomic level. The main difference between the two is that the color force acts on quarks, while the strong force acts on both quarks and gluons.

2. How do the color and strong forces work?

The color force is responsible for binding quarks together to form protons, neutrons, and other hadrons. It is mediated by gluons, which carry the color charge. The strong force, on the other hand, is responsible for holding the nucleus of an atom together. It is also responsible for the binding energy that keeps the nucleus stable.

3. Are the color and strong forces related to each other?

Yes, the strong force and color force are closely related as the strong force is a result of the color force. The color force is what binds quarks together to form particles, and the strong force is the residual effect of this interaction between quarks.

4. Can the color and strong forces be seen or measured?

No, both the color and strong forces are not directly observable or measurable. They are fundamental forces of nature that can only be studied through their effects on particles and their interactions with other fundamental forces, such as the weak and electromagnetic forces.

5. How do the color and strong forces impact the universe?

The color and strong forces are essential for the formation and stability of matter in the universe. Without these forces, particles would not be able to bind together to form atoms, and thus, the universe as we know it would not exist. They also play a role in nuclear reactions and the evolution of stars.
