IPA: /ˌkroʊməˈdaɪnæmɪks/
KK: /kroʊmoʊdaɪnæmɪks/
The study of how quarks interact with each other through a force called the strong force, which involves particles known as gluons.
In particle physics, chromodynamics helps explain how quarks combine to form protons and neutrons.
Chromodynamics is formed from "chroma" (from Greek "chroma", meaning color) and "dynamics" (from Greek "dynamis", meaning power or force). The term refers to the study of the dynamics of color charge in quantum chromodynamics, which is a fundamental theory in particle physics.
Think of 'color' ('chroma') and 'force' or 'power' ('dynamis') to remember that chromodynamics deals with the forces related to color charge in particles.
