What is the equivalence method When I read the notes today, the notes were too messy

What is Equivalence?

The equivalence method is a scientific method of thinking that transforms complex physical phenomena and physical processes into simple physical phenomena and physical processes to study and deal with them. It is an important method of physics research. In secondary school physics, resultant force and component force, combined motion and partial motion, total resistance and partial resistance, average value, effective value, etc., are all introduced according to the concept of equivalence.

In the learning process, if this method can be infiltrated into the analysis of physical processes, it will not only make our analysis and solution of physical problems easier, but also be of great help to flexibly use knowledge and promote the transfer of knowledge, skills and abilities. When solving problems, the most common thing used is to replace the real thing with the model.

"Equivalence" does not mean that all aspects of a thing have the same effect, but rather emphasizes the effect of one aspect. Therefore, it is important to clarify under what conditions, in what scope, and in what aspects different things are equivalent. Equivalent substitutions for the following factors can often be considered:

Research objects, physical models, physical states, physical processes, physical effects, etc.

The diary should be written by yourself, and if you let someone else do it, it is a violation of your privacy. This is your own homework, do you have to let others do all your homework? That's not right.

To be a good student, you have to do your homework carefully, you have to do it yourself, what if your teacher is here? Do you still dare to ask such a question? I believe in you, you can do it!

Write the diary on your own! Be a good student! I firmly believe that you can do it!

Write about what happened this week, even if it is a little subtle, but what is still in your mind now, maybe you will forget it in two weeks, but after sending it back, you will smile at it.

Write your thoughts on the weekend, you can open your mind and meditate.
