What to choose for Physics General Elective 5, what to take for Physics General Elective

I don't know what form of physics you are taking in the college entrance examination now, I am a science student who graduated from Jiangxi in 2011, and we both studied physics electives at that time, but there are two questions in the elective part of the college entrance examination, which are from 3-4, 3-5, and 2 questions. To be honest, both books are quite useful, 3-4, the college entrance examination elective questions are relatively simple (most people think so), and the momentum part of 3-5 is helpful for solving many physics problems. So if you have to specialize in one book, I recommend you choose 3-4, but the momentum in 3-5 should not be unknown at all, and some of the commonly used formula models still need to be memorized.

Another note: I actually focused on 3-5 at that time, mainly for two reasons, one is that I am better at momentum, and the other is that if I focus on 3-5, then 3-4 things can be completely ignored, after all, 3-5 is difficult momentum, even if you choose 3-4, the momentum part of 3-5 is still impossible to completely abandon, so you choose it yourself according to the situation.

The school chooses two books, and you choose one of them, so when you talk about the other book, do you go to do it?

Let's learn both, it's not too difficult to take electives. Both of these books are of great help in understanding the physics system completely.

Being lazy is not a good idea.

In the college entrance examination, it is generally difficult to say which question is simple. Overall, it's not that difficult.

It's better to choose 3-4, 3-5 is too difficult, momentum, atomic physics is more troublesome!

In fact, it is the same in all books, mechanical vibration and mechanical waves are more difficult to understand, but the exam questions are more regular; The momentum is more difficult to understand, but the regularity is also stronger, so which of the two books is the same, it is not easy to understand, but the exam questions are not difficult, the regularity is strong, and there are two test points, mechanical wave and light; Momentum and Atomic Physics.

I'm also a physics teacher, and we just changed the curriculum this year, and we can't make up our minds, so I suggest you study both books and study around the syllabus.

Electives 3-3, 3-4, 3-5

3-3: Theory of meta-fiber dynamics, laws of gases, changes in solids, liquids and states of matter, laws of thermodynamics. (Thermal. ）

3-4: Introduction to Mechanical Vibration, Mechanical Eraser Wave, Optics, and Relativity. (Boscience.) 3-5: Conservation of momentum, atomic physics, wave-particle duality. (Physics and momentum of the original beam pose.) ）

1. The positioning of elective and compulsory courses is different

1. Electives: Electives are an extension on the basis of compulsory courses. Elective courses are positioned to expand and improve on the basis of compulsory courses, focusing on the appreciation and cultivation function of courses, guiding students to conduct in-depth exploration and research, and improve literacy.

2. Compulsory: The knowledge is relatively broad and the scope is relatively large.

2. There is a different evaluation system for elective and compulsory courses

1. Electives: Elective courses are only "electives", not compulsory courses, nor are they simply copied from the university's elective course model, but formulate reasonable course objectives according to the actual situation of students, carry out moderate expansion in depth and breadth, advocate research, and attach importance to students' independent learning.

2. Compulsory: The knowledge is relatively in-depth, and the understanding needs to deepen the cherry blossom dress. The application of knowledge is strong, and the ability needs to be improved.

Electives are also to be learned, electives are optional questions in the college entrance examination, and there are generally two or three optional questions, requiring candidates to choose only one of the questions to answer.

High School Physics Learning Methods:

Regardless of the difficulty of the problem, you should try to draw a picture, some can draw a sketch, some need to draw an accurate map, and use a compass, triangle, protractor, etc., to show the geometric relationship.

Drawing can change the abstract thinking of the spine base to the image of thinking, and grasp the physical process more accurately. With graphs, state analysis is fixed, dead, and intermittent, while dynamic analysis is alive and continuous.

Listen carefully in class and try to be as distracted as possible. Don't give up listening to the lecture because the content of the teacher's lecture is simple, if this situation does occur, it can be regarded as review and consolidation. Try to be consistent and synchronized with the teacher, and you can't do it yourself, otherwise it will be equivalent to complete self-learning.
