2. Have a qualitative understanding of the physical knowledge around you.

3. At the same time, it is also applied to life. The main purpose of learning physics knowledge is to explain various phenomena in life with physical knowledge, analyze the causes of various problems with physical knowledge, and find out the methods and measures to solve related problems.

Requirements for senior high school entrance examination: The development of science and technology is the first step for society to make progress. Another important purpose of studying physics is to master and understand the knowledge of physics, and to be able to use this knowledge flexibly to innovate, explore unknown fields and find new answers, which is the development of science and technology to a higher field.

This is also the direction and trend of physics senior high school entrance examination proposition. Physics in the senior high school entrance examination is more and more flexible, which tends to students' independent thinking and focuses on students' design ability. For the experimental examination, the weight is heavier and the experimental questions are more diverse.

Extended data

To learn physics, we should understand three foundations. (that is, the basic concepts should be clear, the basic laws should be familiar, and the basic methods should be skilled. )

There is a separate question. Do some problems independently with good quality and quantity (meaning not relying on others). There must be a certain number of topics, not too few, but also a certain quality, that is to say, there must be some difficulty. Anyone who studies mathematics and physics can't learn this level well. Solving problems independently may sometimes be slow, sometimes you have to take detours, and sometimes you can't even solve them, but these are normal and the only way for any beginner to succeed.
