What books are optional and compulsory in physics in senior two?
According to the requirements of the examination syllabus, elective courses 3- 1, 3-2 and 3-5 are compulsory, and elective courses 3-3 (thermodynamics) and 3-4 (optics, vibration and wave) are optional modules. Due to historical reasons, most schools in Guangdong only learn 3-3, so I won't introduce 3-4 in detail here.
Compared with Grade One, the content of Grade Two is more and more abstract, because the physics class hours increase after Grade Two, so more teaching content can be basically completed.
What is the main content of physics in senior two?
Elective course 3- 1 in the second semester of senior high school, chapter 1 electrostatic field, which is closely related to the flat throwing movement in the second semester of senior high school; The second chapter is a relatively independent chapter, based on junior high school electricity. The electrical experiments that must be tested in the college entrance examination over the years are all from this chapter, and the general difficulty is not small; The third chapter, magnetic field, is closely related to the circular motion in the next semester of senior three.
If Grade One studies the motion of objects from a macro perspective, Grade Two mainly studies the motion of objects from a micro perspective, which requires higher knowledge of circles and tangents in plane geometry. Recognizing this arrangement of textbooks, students will understand why the physical content of senior two is so abstract.
The remaining physics in Senior Two is 3-2 electromagnetic induction, alternating current and sensors, 3-5 law of conservation of momentum, wave-particle duality, atomic structure and nucleus, 3-3 theory of molecular dynamics, state changes of gases, solids, liquids and substances, and laws of thermodynamics. The electromagnetic induction of 3-2 and the law of conservation of momentum of 3-5 are two important and difficult contents. In addition, it is not too difficult to choose 3-3 for thermodynamic content, but it accounts for 15 in the college entrance examination, which is relatively high.
From the above analysis, it can be seen that there are many overall contents of physics in Grade Two, the concepts are further increased, and the difficulty is greatly increased compared with Grade One. A considerable number of students are very uncomfortable with physics study in senior two, and there are some corresponding suggestions for science students in senior two:
First, don't relax your understanding of every new physical concept. Once you find that some concepts you have learned before have been forgotten or confused, you must find the original text of the textbook, so that the newly learned knowledge can be solid and stand the test.
Secondly, if you do encounter learning confusion, for example, you think you can understand everything in class, but you can't do the questions, it depends on whether it is because of other reasons, such as the basic influence of mathematics. For example, you need to use a lot of knowledge about circles in the magnetic field, so you should pay close attention to reviewing the units of circles in senior three.
For example, the unit of constant current, we can look back at the voltage and current properties of series-parallel circuits in junior high school physics, instead of blindly looking at the physical knowledge we are learning now. Physics in Grade Two is much more difficult than that in Grade One, and it has a lot to do with previous knowledge, but the score is really high, which deserves more efforts.
