Physics is a natural science that deals with the study of matter and energy, their properties, interactions, and transformations. It seeks to explain the behavior of matter and energy at the most fundamental level, from the subatomic particles that make up matter to the largest structures in the universe. Physics covers a broad range of topics, including mechanics, thermodynamics, electromagnetism, optics, atomic and nuclear physics, and quantum mechanics. It uses mathematical models and experimental methods to describe and analyze natural phenomena, from the motion of objects to the behavior of subatomic particles. The applications of physics are diverse, ranging from developing new technologies and materials to understanding the fundamental nature of the universe.
