Physics is the branch of science that explores the fundamental principles governing the universe, focusing on matter, energy, space, and time, and their interactions. It seeks to understand the rules that dictate how everything, from subatomic particles to galaxies, behaves. Core areas include mechanics, electromagnetism, thermodynamics, quantum mechanics, and relativity, each addressing different scales and phenomena. Physics is foundational to other sciences, providing insights into the forces and energies that shape the natural world, from the motion of planets to the behavior of light.

The field is divided into theoretical and experimental approaches, with theoretical physicists developing mathematical models to predict phenomena, while experimentalists test these predictions through observation and measurement. Physics drives technological innovation, leading to advancements like electricity, lasers, and medical imaging. It also tackles profound questions, such as the nature of dark matter or the origin of the universe. By uncovering the underlying laws of reality, physics not only expands human knowledge but also transforms how we interact with the world through engineering, medicine, and beyond.
