In physics, a quark is a fundamental constituent of matter. ⚛️ It's a tiny particle that combines with others to form hadrons like protons and neutrons, which are themselves parts of atoms. Quarks have fractional electrical charge, unlike the protons and electrons we're more familiar with. There are six "flavors" of quarks: up, down, charm, strange, top, and bottom. They're like the basic Lego bricks of the universe! 🧱 You can't isolate a single quark; they're always found bound to other quarks.
