What is definitions of physical science?

Physical science is a branch of natural science that deals with the study of non-living systems and phenomena. It involves the application of mathematical models and scientific methods to experimental and observational data to establish the fundamental laws of nature. Physical science can be further divided into two major disciplines: physics and chemistry. Physics is concerned with the study of matter and energy, the interactions between them, and the laws that govern their behavior, while chemistry is focused on the study of the composition, structure, properties, and changes of matter. Together, these disciplines form the foundation of many modern technologies and have contributed significantly to our understanding of the universe and natural phenomena.
