2. Physics is the knowledge of the laws of nature; More broadly, physics explores the analysis of phenomena that occur in nature in order to understand their rules.
3. Physics is a discipline that studies the most general laws of motion of matter and the basic structure of matter. As a leading discipline in the natural sciences, physics studies the most basic forms and laws of motion of all matter, from the universe to elementary particles, and thus becomes the research foundation of other natural science disciplines.

The interrelationship of the genera.
Physics includes: physical phenomena, the structure of matter, the interaction of matter, and the laws of motion of matter.
Physics can be divided into two parts: micro and macroscopic, macroscopic is not to analyze the effect of a single particle group and directly consider the overall effect, which has appeared in the earliest days, and the theory of microphysics has gradually improved with the development of science and technology.

Classification of Physics:
Newtonian mechanics and rational mechanics study the basic laws of mechanical motion of objects and the laws of relativity in time and space.
Electromagnetism and electrodynamics study electromagnetic phenomena, the laws of electromagnetic motion of matter, and the laws of electromagnetic radiation.
Thermodynamics and statistical mechanics study the statistical laws and macroscopic manifestations of the thermal motion of matter.
The theory of relativity studies the effects of high-speed motion of objects and the associated dynamical laws.
Quantum mechanics is the study of the phenomena of microscopic matter motion and the basic laws of motion.
Particle Physics, Nuclear Physics, Atomic and Molecular Physics, Solid State Physics, Condensed Matter Physics, Laser Physics, Plasma Physics, Geophysics, Biophysics, Astrophysics.

Anonymous users2024-02-09Physics includes branches such as mechanics, thermal, electrical, optical, and atomic physics.
Our world is made up of matter, and the way matter exists is the movement of objects. That is to say, all objects are in motion, and physics is to study the laws of motion of all objects. The classification of the motion of different objects is divided into branches of physics such as mechanics (mechanical motion), heat (thermal motion), electricity (motion of electric charges and fields), optics (the fastest speed of light), and atomic physics (the motion of atomic nuclei and elementary particles).
Physics is not just a theory and formula, nor is it a question on the test paper, physics is all around you. I recommend "Grimace Physics Lesson", ** penmanship to write the history of physics, very interesting.
The negative charge from point A to point B does deceleration motion, the electric field force hinders the movement, and does negative work, so the potential of point A is higher than point B, and the TV energy of point A is lower than point B, and the potential difference between the two points of AB can be found by the kinetic energy theorem, and the potential of point A can not be found, and the electric potential of point A is wrong and B is wrong and D is right, and it can be seen from Figure B that the acceleration of the charge motion is different, so the electric field is a non-uniform electric field and the electric field strength C pair cannot be found.
Teach you how to like you, instead of having a teacher? According to the Department of Education and Skills, students in school will have their own way of teaching, and in the future there will be no more problems, such as finding enough teachers.
