What area of study does physical science encompass?

The correct choice focuses on the study of matter and energy, which are fundamental concepts in physical science. Physical science is generally divided into various disciplines such as physics, chemistry, and astronomy, all of which explore different aspects of the physical universe.

In physics, for example, you analyze the laws of motion, force, energy, and the behavior of objects. Chemistry looks at the composition, structure, properties of matter, and how substances interact and change. Together, these areas provide a comprehensive understanding of the physical world around us, including how matter interacts with energy.

The other options refer to areas that do not fall under the umbrella of physical science. The study of mental processes and behaviors pertains to psychology, while the study of electrical circuits is a specific application often found in engineering rather than a core aspect of physical science. The study of organic compounds is a branch of chemistry focused specifically on carbon-containing compounds, but it is not as broad as the overall focus of physical science, which encompasses all matter and energy.
