Physical science is a science which is related to study of non-living things.
With the advancement of knowledge, the subject has become so vast and is divided into many branches and sub-branches.
Branches of physical science include
1. Physics: Physics is a science which deals with the study of outer aspects of matter in relation to space and time. It also deals mainly with concepts of motion, energy, force, pressure, light, acceleration, gravity etc. We can understand how the daily life aspects occur in a specified manner.
2. Chemistry: Unlike physics, it deals with inner aspects of matter and material. It defines matter in terms of atoms (comprising of protons, neutrons, electrons) molecules, elements in nature, their interactions and properties. It defines how matter is made of elements, the physical properties and chemical properties of material around, its interactions with other, decomposition, etc. It is a vast subject further divided into many sub-branches like organic chemistry, natural chemistry, etc. You can also read more on branches of chemistry.
3. Astronomy: As the name indicates, this is the study of astral objects like galaxies, stars, planets, moons, asteroids, comets, etc. It also tries to discover their presence in-the universe, their dimensions, physical, chemical nature, motions, the atmosphere on them, etc. Further, it also deals with different radiations and electromagnetic influences on earth and other celestial bodies.
4. Earth science: This science is purely concerned with the knowledge of earth, its internal and external atmosphere, the presence of useful minerals, water resources, structure and layers of earth, etc. It is also so wide and has many sub-branches for study.
5. Material science: This science is concerned purely about the material and its properties. It is interdisciplinary subject and is application oriented. It aims to design new materials out of the knowledge related to chemistry, physics. It tries to combine metallurgy, chemistry, solid-state physics and even ceramics. The aim of this science is to create a new material which is non-existent in nature previously.
6. Geology: It is a part of earth science and is concerned with rocks and other solid earth materials. The subject also tries to understand the process of earthquakes, volcanoes, landslides, etc. The subject also tries to locates minerals, metals, oil, water, etc.
