Physics

Physics is the scientific study of the fundamental principles governing the behavior of matter and energy in the universe. It explores the nature of space, time, motion, forces, and the interactions between particles and fields.

Physicists seek to formulate laws and theories that describe the fundamental forces shaping the cosmos, from the microscopic world of subatomic particles to the vastness of galaxies. Divided into classical and modern physics, the discipline encompasses mechanics, electromagnetism, thermodynamics, quantum mechanics, and relativity.

Physics not only provides a framework for understanding the physical world but also drives technological innovations, shaping our comprehension of reality and inspiring advancements in various scientific and technological domains.
