Physics is the branch of natural science that studies the non-living system, unlike the science of life. In turn have many branches, each referred to as "physical science", together called "physics". However, the term "physical" creates unwanted differences, rather arbitrarily, since many branches of physical science also study biological phenomena and chemical branches such as organic chemistry.

Definitions
Physics can be described as all of the following:
- A branch of science (a systematic enterprise that builds and organizes knowledge in the form of explanations and predictions that can be tested about the universe).
- Branches of natural science - natural science is the main branch of science that tries to explain and predict natural phenomena, based on empirical evidence. In the natural sciences, the hypothesis must be scientifically verified to be considered a scientific theory. Legitimacy, accuracy, and social mechanisms that ensure quality control, such as peer assessment and repetition of findings, are among the criteria and methods used for this purpose. Natural science can be broken down into two main branches: life sciences (eg biology) and physical sciences. Each of these branches, and all its sub-branches, is called natural science.

Branch of physical science
- Physics - the natural and physical sciences involving the study of matter and its motion through space and time, along with related concepts such as energy and style. More broadly, this is a general analysis of nature, which is done to understand how the universe behaves.
- Physics branches
Astronomy - studying celestial bodies (such as stars, galaxies, planets, moons, asteroids, comets and nebulae), the physics, chemistry, and evolution of such objects, and phenomena emanating from outside the Earth's atmosphere, including explosive supernovas , gamma-ray bursts, and cosmic microwave background radiation. - The astronomical branches
- Chemistry - studying the composition, structure, properties, and material changes. In this world, chemistry deals with topics such as the properties of individual atoms, the way atoms form chemical bonds in the formation of compounds, the interaction of matter through intermolecular forces to give the material its general properties, and the interaction between substances through chemical reactions to form different substances.
- Chemical branch
- Earth Sciences - a term that includes all referring to the field of science dealing with planet Earth. Earth science is the study of how the natural environment (ecosphere or Earth system) works and how it evolves into its current state. These include studies of the atmosphere, the hydrosphere, the lithosphere, and the biosphere.

History of physical science
Physics - the branch of science that studies matter and its motion through space and time, along with related concepts such as energy and style. Physics is one of "basic science" because of other natural sciences (such as biology, geology, etc.) dealing with systems that seem to obey the laws of physics. According to physics, the physical laws of matter, energy, and the fundamental forces of nature govern the interactions between particles and physical entities (such as planets, molecules, atoms, or subatomic particles). Some of the basic pursuits of physics, which include some of the most notable developments in modern science in the last millennium, include:
- Describe the nature, measure and measure their body and motion, dynamics etc.
- Newton's motion law
- Mass, style and weight
- Momentum and conservation of energy
- Gravity, the theory of gravity
- Their energy, work, and relationships
- Motion, position, and energy
- Various forms of Energy, their interconversion and the inevitable loss of energy in the form of heat (thermodynamics)
- Energy conservation, conversion, and transfer.
- Energy sources transfer energy from one source to another.
- The kinetic molecular theory
- Phase material and transition phase
- Temperature and thermometer
- Energy and heat
- Heat flow: conduction, convection, and radiation
- Four laws of thermodynamics
- Wave and sound principle
- Principles of electricity, magnetism, and electromagnetism
- Principles, sources, and light properties
The basic principle of astronomy
Astronomy - the science of celestial bodies and their interactions in space. His studies include the following:
- The life and characteristics of stars and galaxies
- The origin of the universe. Physics uses the theory of Big Bang as a generally accepted scientific theory of the origin of the universe.
- The Solar System is heliocentric. Ancient cultures see the Earth as the center of the Solar System or the universe (geocentrism). In the 16th century, Nicolaus Copernicus advanced the ideas of heliocentrism, recognizing the Sun as the center of the Solar System.
- The structure of the solar system, planets, comets, asteroids, and meteors
- The shape and structure of the Earth (roughly round, see also Spherical Earth)
- Earth in the Solar System
- Time measurement
- Moon compositions and features
- Earth and Moon Interactions
(Note: Astronomy should not be equated with astrology, which assumes that human destiny and human affairs are generally correlated with the positions of clear astronomical objects in the sky - although two fields have the same origin they are very different: astronomers embrace scientific methods, while astrologers no.)
Basic principles of chemistry
Chemistry - the branch of science that studies the composition, structure, properties and material changes. Chemistry is primarily concerned with atoms and molecules and their interactions and transformations, for example, the nature of chemical bonds formed between atoms to create chemical compounds. Thus, chemistry studies the involvement of electrons and various forms of energy in photochemical reactions, oxidation-reduction reactions, material phase changes, and the separation of mixtures. Preparation and properties of complex substances, such as alloys, polymers, biological molecules, and pharmaceutical agents are considered in special chemical fields.
