Fundamental Particles and Forces

The video tutorial covers nuclear physics and the standard model, explaining the structure of atoms, the concept of mass-energy equivalence (E=MC²), and the role of atomic mass units. It introduces the four fundamental forces of nature and discusses antiparticles and the standard model, including quarks and leptons. The tutorial also touches on the Higgs boson and the classification of matter into hadrons and leptons.
