Quark - Wikipedia
A quark (/ k w ɔːr k, k w ɑːr k /) is a type of elementary particle and a fundamental constituent of matter.Quarks combine to form composite particles called hadrons, the most stable of which are protons and neutrons, the components of atomic nuclei. Due to a phenomenon known as color confinement, quarks are never directly observed or found in isolation; they can be found only within ...
Quarks - HyperPhysics Concepts
Quarks. Quarks and Leptons are the building blocks which build up matter, i.e., they are seen as the "elementary particles". In the present standard model, there are six "flavors" of quarks. They can successfully account for all known mesons and baryons (over 200). The most familiar baryons are the proton and neutron, which are each constructed from up and down quarks.
quark | Definition, Flavors, & Colors | Britannica.com
Quark, any member of a group of elementary subatomic particles that interact by means of the strong force and are believed to be among the fundamental constituents of matter.Quarks associate with one another via the strong force to make up protons and neutrons, in much the same way that the latter particles combine in various proportions to make up atomic nuclei.
7 Strange Facts About Quarks - Live Science
The first quarks appeared about 10^minus 12 seconds after the universe was formed, in the same era where the weak force (which today is the basis for some radioactivity) separated from the ...
Definition of Quarks in Physics
A quark is one of the fundamental particles in physics. They join to form hadrons, such as protons and neutrons, which are components of the nuclei of atoms. The study of quarks and the interactions between them through the strong force is called particle physics.
Quark - definition of quark by The Free Dictionary
quark 1 (kwôrk, kwärk) n. 1. Any of a class of six fundamental fermions, two in each of the three generations, one having an electric charge of - 1/3 , the other, + 2/3 , comprising the down, up, strange, charm, bottom, and top quarks. Quarks are the basic components of all hadrons. 2. Any of the six quarks' associated antiparticles, the antiquarks ...

Quarks | Article about Quarks by The Free Dictionary
Quarks. The basic constituent particles of which elementary particles are understood to be composed. Theoretical models built on the quark concept have been very successful in understanding and predicting many phenomena in the physics of elementary particles.
What Are Quarks? » Science ABC
The two lightest quarks (in terms of mass) are Up and Down, followed by Strange, Charm, Bottom and Top. Top is not only the heaviest, but also the final quark to be discovered, back in 1995.
