College physical mechanics, heat, optics, electromagnetism, electrodynamics. These five are basic physics. If physics is compared to a building, then these courses belong to the foundation of the building, followed by four major mechanics: theoretical mechanics, electric collision mechanics, thermal statistical mechanics and quantum mechanics, which are equivalent to the pillars of the building. College physics is mainly about learning basic theoretical physics and four major mechanics. The basic theoretical physics is mechanics, heat, optics, electromagnetism and electrodynamics. The four major mechanics are theoretical mechanics, quantum mechanics, electric shock mechanics and thermal statistical mechanics. There are also some compulsory courses in physics, such as basic physics experiments, basic extension subjects, such as modern optics and solid state physics, as well as some courses in mathematics, physical methods and digital circuits. Through the education of college physics, students can understand the basic laws of the structure and movement of natural substances. Mechanics and electromagnetism are the main courses of college physics in engineering colleges.
