The study of the physical universe and its contents is called "physics." Physics explores the fundamental principles that govern matter, energy, space, and time. It encompasses a wide range of topics, including mechanics, thermodynamics, electromagnetism, and quantum mechanics. Physicists seek to understand the laws of nature, from the behavior of subatomic particles to the dynamics of galaxies. This field is essential for advancing technology and deepening our comprehension of the universe. Physics plays a critical role in various scientific disciplines and has profound implications for everyday life, influencing everything from medicine to engineering.
