How can I get a full score in junior high school physics, and how can I improve my physical thinking

In the process of learning physics, what we have to learn is not only the formula of the solution in the physics book, but more about the thinking of physics, we should learn to think about the problem with macro thinking, and think about the problem comprehensively from all aspects, so as to better improve our physics scores.

Be sure to listen carefully to the teacher's lectures in class, pay attention to do more questions after class, and ask the teacher if you don't understand any questions.

If you are in junior high school physics, you must lay a good foundation, and then do more related problems. Be sure to pay attention, and if you don't understand, ask the teacher.

Grasping the basics, connecting with reality, understanding each definition, and seeing the essence through phenomena are the foundation of learning junior high school physics well, and it is also the foundation for further learning of high school physics!

Relying on brushing questions to go to high school may be abolished in one month after the start of school!

The ideal is to get a full score or very simple, and to improve the thinking ability of physics is to practice more questions.

In terms of solving circuits, it is difficult to figure out whether the resistors are connected in series or parallel without drawing circuit diagrams.

What workbooks are there about junior high school physics.

Junior high school physics, it's so easy! It's almost effortless.

Be sure to keep the definitions and formulas in mind and practice a lot.

The new knowledge of physics that will be learned in the third year of junior high school mainly involves "electricity and magnetism" in motion and interaction, "mechanical energy", "internal energy", "electromagnetic energy", "transformation and conservation of energy" and "energy and sustainable development" in energy.

Specifically, the physical concepts and physical phenomena to be studied mainly include work, power, mechanical efficiency, mechanical energy, internal energy, heat, circuit, current, voltage, resistance, electrical work, electric power, magnetic effect of current, electromagnetic induction, and the effect of magnetic field on current. The physical laws to be learned mainly include the principle of leverage, the principle of work, the characteristics of series and parallel circuits, Ohm's law, Joule's law, and the law of conservation of energy. The physical models to be learned mainly include levers, pulleys, etc.; The substances to be understood mainly include magnetic fields, electromagnetic waves, energy, etc.; The instruments to be used mainly include ammeters, voltmeters, sliding rheostats, etc. Among them, the main learning requirements are: understanding the concept of power, understanding mechanical efficiency, understanding Ohm's law, understanding electrical work, and understanding electric power, which are not only the focus of learning, but also the difficulty of learning.

The knowledge points listed above are also the test points of the high school entrance examination.

In order to learn physics well and achieve ideal results in the high school entrance examination, students should pay attention to the following points in the learning process of the third stage of junior high school:

1) Based on the classroom, lay a solid foundation. The classroom is the main front for learning the basic knowledge and basic skills of physics, and only by grasping the classroom, grasping the "double base", and learning the necessary methods, will there be the possibility of expansion and improvement.

2) Pay attention to the process and learn research methods. Physics is an experimental science, learning physics should pay attention to the scientific process, for each experiment, not only to know how to do it, but also to understand why it is done, and to be able to make a proper assessment of the process and results; In addition to learning physics knowledge, students should also learn related research methods, such as: transformation method, control variable method, comparison method, ideal experimental reasoning method, induction method, equivalent method, analogy method, ideal model method, etc.

3) Strengthen training and improve the ability to transfer and apply knowledge. Doing some supplementary exercises outside of class is a more effective measure to digest and consolidate the knowledge learned and expand and improve. In the process of problem solving, attention should be paid to cultivating and improving the ability to review problems.

4) Optimize learning methods and improve learning efficiency. If you encounter difficulties and doubts in learning, due to the intense learning in the third stage of junior high school, you can't spend a lot of time slowly "grinding", you should mark it well, discuss it with your classmates, and it is best to seek the teacher's answer, understand the process, and master the method.

5) Induction, generalization, series of links to form a comprehensive ability. In the usual learning process, summarize the knowledge learned as necessary, and connect the newly learned knowledge with the previous content, pay attention to their similarities and differences, and achieve coherence. For example, when learning the concept of power, you can think comprehensively against the concept of speed that you have already learned.

6) Standardize the answer and pay attention to the details. "Specification" is mainly reflected in short-answer questions, drawing questions, and calculation questions in the exam. In the high school entrance examination over the years, it is not uncommon to lose points due to non-standard answers.
