The primary concern of physics is focused on exploring the laws of movement and energy. This field of science seeks to understand the fundamental principles that govern the physical universe, analyzing how objects interact, how forces influence motion, and how energy is transformed from one form to another. Physics delves deep into concepts such as mechanics, thermodynamics, electromagnetism, and quantum physics, all of which are essential for explaining how the natural world operates.
Conversely, the other options are associated with different scientific disciplines. Understanding genetic variation pertains to biology and the study of heredity and evolution. Studying the chemical composition of matter falls under the realm of chemistry, which investigates substances, their properties, and how they react. Analyzing human behavior is the focus of psychology and social sciences, which examine mental processes and social interactions. Each of these fields addresses unique aspects of science, whereas physics is primarily concerned with the fundamental laws that dictate how matter and energy behave in the universe.
