What are the major branches of physical science?

Answer 1

In general, the Physical sciences study non-living matter, energy, and their interactions. Earth science, Chemistry, Mathematics, and Physics are, traditionally, the main branches of the physical sciences.

There are many sub-branches. To name only a few:

Aerodynamics: Motion of air and its interaction with moving objects;

Astronomy: Motion and character of the universe and the bodies within it;

Astrophysics: Properties, origin, and evolution of celestial bodies;

Biochemistry: Chemistry of living organisms;

Classical mechanics: Behavior of objects in a system of forces;

Computer sciences: Fundamentals of Information Management and computation;

Earth Sciences: Encompassing term for the study of the planet, Earth;

Electricity: Fundamentals of electrical energy, its transport, and uses;

Electronics: Emission, behavior, and effects of electrons;

Engineering (most): Development of technology from new discoveries;

Geography: Earth's features and the distribution of life over it;

Geology: Earth's Origin, History, and structure

Mechanics: Motion and behavior of objects under force;

Fluid Dynamics: Motion and behavior of fluids and gases under force;

Optics: Behavior and properties of light;

Physical Chemistry: Application of any of several physical sciences to chemical systems;

Quantum mechanics: Structure and behavior of atoms and sub-atomic systems;

Statistical mechanics: Predicts behavior of materials from atomic & molecular observations;

Thermodynamics: Transformational relationships between heat and other energy forms.

etc.
