Physical science is a branch of natural science that studies non-living systems and the physical universe, in contrast to life sciences which focus on living organisms

. It investigates the nature and properties of matter and energy and the fundamental principles governing their interactions

Key aspects of physical science:

• It is concerned with the inorganic world and non-living matter

• It uses empirical observation, experimentation, and mathematical modeling to explain natural phenomena and develop testable theories

• It includes both basic science (advancing scientific theories) and applied science (using scientific knowledge for practical goals)

Major branches of physical science:

• Physics: Study of matter, energy, and the forces governing their interactions, including motion, gravity, electromagnetism, thermodynamics, and quantum mechanics

• Chemistry: Study of the composition, structure, properties, and changes of matter, focusing on chemical reactions and interactions

• Astronomy: Study of celestial bodies, the universe’s structure, and cosmic phenomena like stars, planets, and galaxies

• Earth Science: Includes geology, meteorology, oceanography, and environmental science, focusing on Earth's composition, atmosphere, climate, and natural events

Physical science forms the foundation for many technologies and scientific advancements that impact daily life, such as medical imaging, renewable energy, and communication systems

. In summary, physical science is the systematic study of the non-living physical world, encompassing disciplines like physics, chemistry, astronomy, and earth sciences to understand the laws and properties of matter and energy
