Branches of Physics 2026
Branches of Physics Introduction Physics is the branch of science that explores the fundamental principles governing the universe. From the smallest subatomic particles to the vastness of galaxies, physics investigates how matter behaves, how energy flows, and how forces interact. It offers logical explanations for natural phenomena and establishes scientific laws that describe the function of the physical world. Whether it is the motion of planets, the behaviour of light, the structure of atoms, or the nature of time and space, physics provides the essential framework to understand reality. Physics is not only theoretical but also highly practical. It forms the basis of modern technology—electricity, communication systems, medical equipment, transportation, energy generation, and countless tools of daily life rely directly on physical principles. Thus, physics acts as the connecting bridge between scientific understanding and technological advancement. ⸻ Chapter 1: The Origin and Development of Physics 1.1 Ancient Beginnings Early humans…
