The primary focus of physics is to understand the fundamental principles that govern the behavior of matter and energy in the universe. This scientific discipline investigates the properties and interactions of various forms of energy, including mechanics, heat, light, electricity, magnetism, and atomic structure. Through experimentation and mathematical modeling, physicists aim to describe how objects move, how forces interact, and the fundamental nature of the universe. By achieving a deeper comprehension of these concepts, physics lays the groundwork for advancements in technology and a better understanding of the natural phenomena around us.
