what is the physics?

Physics is a natural science that involves the study of matter and energy and their interactions. It encompasses a wide range of phenomena, from the smallest subatomic particles to the largest structures in the universe. Physicists use mathematical models and experiments to better understand the behavior of the physical world, from the behavior of matter and energy at the atomic and subatomic level to the study of large-scale phenomena such as the formation of galaxies and the behavior of black holes. The applications of physics are vast and include fields such as engineering, medicine, and technology.
