Physics is the branch of science that explores the fundamental principles governing the behavior of matter and energy in the universe. It encompasses a wide range of topics, from the smallest subatomic particles to the vastness of cosmic phenomena. By employing mathematical models and experimental methods, physicists seek to understand the laws that dictate the interactions of forces, motion, and energy transformations. This discipline not only enhances our comprehension of the natural world but also drives technological advancements that shape modern society.
