Through the analysis, it is not difficult to see that the whole volume weakens the synthesis between plates, strengthens the synthesis within plates, and avoids complicated problems as a whole, so it is difficult to see a large number of problems pieced together by knowledge points. It pays attention to the examination of the basic concepts, basic laws and core thinking methods of physics, and the process of solving problems does not depend on special skills. As long as you master the basic methods, most problems can be solved, which has great grasp and advantages for students who pay attention to the basics.
For example, the multiple-choice question 15 highlights the examination of the basic knowledge of magnetic flux, and the examination method is novel but the knowledge points are simple, while the multiple-choice question 2 1 examines the basic bisection method to find the equipotential surface.
The change of process leads to the diversity of results, and it is difficult to master the solutions to all problems. Students are required to establish a clear process diagram through analysis and understanding, and discuss the key conditions in categories to get the final result trend.
In particular, the last problem is calculated and the basic plate model is investigated. However, because the ground is rough, there will be a scene where the speed and strength change in the middle of the movement, which needs to be re-analyzed. This requires higher process analysis, but for students who have practiced at ordinary times, it will be relatively easy to score.
