Physics is a natural science that seeks to understand the fundamental principles that govern the behavior of the physical universe. It is concerned with describing and explaining the behavior of matter and energy at all scales, from the subatomic to the cosmic.
Physics uses mathematical models to describe the natural world, and relies on experiments and observations to test these models and develop new ones. It is a highly interdisciplinary field that intersects with many other branches of science, including chemistry, biology, and engineering.
Some of the key areas of study in physics include classical mechanics, electromagnetism, thermodynamics, quantum mechanics, and relativity. Physics has many practical applications, including the development of technologies like computers, telecommunications, and medical imaging.
