What is Physical Science and its types

Physical science is a branch of natural Science, It’s deals with non-living systems of the universe, matter, energy, and their interactions. Physical science has broad field of study. that’s including physics, chemistry, astronomy, geology, and meteorology.

Study of physical science plays important role in our daily lives, from the technology we use to the medicines we take. It also contributes to a deeper understanding of the world around us, from the behavior of subatomic particles to the structure and evolution of the universe.

Definition of physical science

Physical Science

physics is a branch of physical science that studies the behavior of matter and energy in the natural world.

Basic principles of physics

Newton’s Laws of Motion

Newton’s law describes the behavior of the object in motion. newton gives 3 laws, First law states that an object at rest will remain at rest, and an object in motion will remain in motion at a constant velocity unless acted upon by an external force. The second law states that the force acting on an object is proportional to its mass and acceleration. The third law states that for every action, there is an equal and opposite reaction.

Conservation of Energy

Conservation of energy principle states that energy cannot be created or destroyed, but can only be converted from one form to another.

Theory of Relativity

This theory describes the relationship between space and time and the behavior of objects in motion.

Quantum Mechanics

In quantum physics we studies the behavior of matter and energy at the atomic and subatomic levels.


Electromagnetism studies the behavior of electric and magnetic fields and their interaction with matter.


In thermodynamics we studies the behavior of heat and its relationship to other forms of energy.


chemistry is a branch of physical science that studies the properties and behavior of matter, including atoms, molecules, and their interactions.

Basic principles of chemistry

Law of Conservation of Mass

Mass of a closed system will remain constant over time, regardless of any physical or chemical changes that occur within the system.

Periodic Table

Periodic table of elements is arrangement of the known elements according to their atomic number, electron configuration, and chemical properties.

Chemical Reactions

Chemical reactions involve the transformation of one or more substances into new substances with different properties.

Acids and Bases

Acids and bases are important classes of compounds that are involved in many chemical reactions.


Solutions are homogeneous mixtures of two or more substances.


astronomy is a branch of physical science that studies celestial objects and phenomena in the universe.

Basic principles of astronomy


Spectroscopy is a technique used by astronomers to study the chemical composition, temperature, and motion of celestial objects by analyzing their electromagnetic radiation.


Cosmology is the study of the structure, origin, and evolution of the universe.

Stellar Evolution

In stellar evolution we study the life cycles of stars their formation, fusion, and death.

Planetary Science

In planetary science we study of the planets, moons, and other objects in the solar system.


Geology is a branch of physical science that studies the Earth’s composition, structure, processes, and history.

Basic principles of geology

Plate Tectonics

Plate tectonics is the theory in which we describes the movement and interactions of the Earth’s lithospheric plates.


In Stratigraphy we study of the layers (strata) of rocks in the Earth’s crust.

Rock Cycle

The rock cycle is the process by which rocks are transformed from one type to another through processes such as erosion, weathering, and metamorphism.

Geologic Time Scale

Geologic time scale is the chronological ordering of geological events and time periods in Earth’s history.


Mineralogy is the study of minerals, which are the building blocks of rocks.


meteorology is a branch of physical science in which we study of the Earth’s atmosphere and the processes that occur within it.

Atmospheric composition

We know that earth’s atmosphere is composed of various gases, including nitrogen, oxygen, and trace gases such as carbon dioxide and water vapor.

Weather systems

large-scale patterns of atmospheric circulation that drive weather and climate.

Climate change

Climate change is a major issue in meteorology. Climate change is caused by a variety of factors, including changes in atmospheric composition, solar radiation, and ocean currents.

Atmospheric optics

Interaction of light with the atmosphere produces a wide range of optical phenomena like rainbows, halos, and atmospheric scattering.


In conclusion, physical science is a broad field of study that encompasses physics, chemistry, astronomy, geology, and meteorology.
