How do you learn physics well in junior high school? How to learn junior high school physics ??? wel

The most important thing in electricity is to master the principles of physics, and the laws of physics are particularly strong.

No matter what kind of problem it is, it has its basic central idea.

And those basic formulas.

To grasp the principle, a very complex problem, just grasp the principle in the middle, and then write it down step by step with the corresponding formula.

Let's say a problem that gives some known, and if you ask for a result, you need some unknowns.

So we apply the formula of the principle of the problem to the known quantities, and then write the unknown quantities step by step.

In fact, a lot of things can be done by writing the formula, step by step, and don't be afraid of trouble.

If it's a circuit, no matter how it's scribbled.

Then slowly simplify.

Physics is the idea of taking some simple problems and then adding them to a basic formula.

As long as you grasp the principle, grasp the fundamentals, take your time, and have some patience, the key is to use the pen, move the stroke, and write the pen.

If you grasp the regularity of physics, you can master physics.

Hope that helps.

Junior high school physics is still simple.

Knowing that finding the root of the problem is actually a very simple formula.

Don't think of physics as difficult.

In fact, it's just a simple formula, and the key is to put it to the pen.

You can't just think about it with your head.

Do more questions, that's how I am, I can't do it at first, and then I get second, starting with the simplest, which is the easiest way and the only way.

Do more experiments to distinguish what resistance, current, and voltage do. If you can afford it, you can buy a model. Also remember the left zero and right fire, this is a must-remember.

The circuit diagram can't be drawn here. You have to remember the circuit diagram, the high school entrance examination is a must!! Why doesn't the bulb light light on, the power supply is connected there, I want to read the physics book!

It's all in the books, and I don't know how to ask the teacher.

Listen carefully in class, follow the teacher, as long as you listen to it, you will feel that physics is actually very interesting, and you must write down the key theorems or something. Just do some more exercises after class.

First of all, master the basics of the textbook proficiently, figure out the principles clearly, don't have to do too many questions, think more and summarize more, and everything will not deviate from its origin.

Do more, see more, think more, that's all!!

Focus on understanding, don't memorize too much, and memorize formulas on the basis of understanding and in the process of using them - so that you can remember them well.

Take some time after class, do exercises, about one or two questions each time, and think more about the difficult ones (the homework assigned by the teacher should be completed carefully).

Take physics experiments seriously.

Finally, the knowledge chain of physics cannot be broken, if there is something in which section or chapter you did not go to class, then you must try to make up for it, otherwise you will not be able to understand it in the following classes.

The above are some of my personal experiences in learning physics, my junior high school and high school physics are okay, you can refer to it.

First of all, you have to make yourself like it, starting with liking your physics teacher; Do a good job of every student experiment, even if it's unusually easy; Memorize every formula by heart, and know the meaning and unit of every physical quantity.
