Strong Nuclear Force

Gluons are actually

tiny globs of glue

 

The Strong Nuclear Force, or Strong Force is the fundamental force interaction between quarks. It is conducted by gluons, which are charged themselves.

 

Charge

There are three types of strong charges, called colors. Each quark carries one color: red, green, blue, antired, antigreen, or antiblue, while gluons carry two (antiquarks have anticolors). Because the net color charge of nuclei is neutral, the strong force usually only interacts noticeably on sub atomic scales. The majority of the strong interaction is between quarks inside subatomic particles. Interestingly enough, Gluons can be attracted to each other independently of quarks.

Quarks often seem to form triplets consisting of differently colored particles, as electromagneticly charged particles will form groups of two particles.

while orange represents repulsion.

 

Force

Unlike gravity, the strong force is governed by a square law. This means that an unobstructed quark's charge should interact on huge scales with distant objects. However this effect is shielded by other quark's charges. The derivative interaction between the quarks is called the residual strong nuclear force, and is thought to be responsible for holding nuclear hadrons together.
