I don't know where you are from in Shandong, but we have finished the first chapter of the elective course 3- 1 in Yantai Senior One. After the second year of high school, I will continue to talk. I have previewed some now.
I'm a student in the experimental class of Yantai No.2 Middle School, science class 14, and I think I can help you ~
The first chapter of 3- 1 will feel disorganized at first, and there are many formulas. I suggest you memorize the formulas and definitions now, so that you can form a knowledge network in your mind and save a lot of time after school starts.
The problems in this chapter are closely related to the knowledge of compulsory one. Especially Newton's three laws. Sports also involve a lot. The main problem is the motion of charged ball in electric field. So compulsory one must be sure to be foolproof.
As for compulsory two, in fact, the first two chapters (curve motion, gravity) have little to do with the first two chapters of elective 3- 1 The magnetic field will involve mechanics, and there will be something that moves in a circle. It seems that gravity is the most useless. If time is short, you can play the first two chapters of compulsory two first. But the law of conservation of mechanical energy in chapter 3 is very important, and the kinetic energy theorem is the most important one. The things in the textbook are very shallow, and many knowledge points directly related to the exam can't be mastered just by reading the textbook. I don't know what reference materials you have, but I can tell you that the material used in our big experiment is "Three-dimensional Design" published by Guangming Daily Press. This information is very good, the knowledge points are thoroughly analyzed and the questions are comprehensive and typical. You can look for it.
In order to ensure that you can understand the things in the class after the start of school, I suggest you do more examples about motion, Newton's three laws and kinetic energy theorem in the reference books. (Note that this is an example). Must be able to skillfully analyze the force of the object, which is the basis of everything.
Elective course 3- 1 chapter 2 is brand-new from the beginning and has little to do with mechanics. So as long as you preview well before class, listen carefully in class, ask more questions and summarize more after class, there will be no problem.
(say something beside the point. I think you didn't listen to the class well in the first year of high school, and your physical thinking may not be cultivated in place. I suggest you think more when you make up lessons. The more you think, the deeper you think, the better If you can't do it, think about it and try your best to get mad. Even if it doesn't work out in the end, it will make your overall thinking take a big step. Tell you the famous words of the physics master in our class-the slower you usually do the questions, the faster you take the exam)
