Start with the straightening exercise at the beginning of the first year of high school. You may think this is an exaggeration! You may also feel that you have learned well in front of you.
Hehe, in my opinion, it's far from it! That's the advice I give. From the ground up!
If you are not convinced, I will give you a small question in the first chapter: an ant crawls away from the hole, and the crawling speed is inversely proportional to the distance from the hole, and it is known that its speed is 1 meter from the hole. How long did it take to climb from the hole to the exit?
Try it! Physics is good at the thickness of a piece of paper! Physics can only be achieved by thinking more!
It's only a freshman in high school, so let's start from scratch!

Every law and theorem concept must be understood.
If you don't understand it, you will get worse and worse if you memorize formulas and solve problems.
Figure out the specific situation of the motion, describe it in terms of speed, acceleration, force, trajectory, etc.
And then figure out why it's the way it is, let's say has the speed changed? Why the change?
What role does force play in this process? How do Newton's laws affect motion?
Does the force change the magnitude or direction of the velocity? Or have both changed?
You must grasp the general direction and summarize what you have learned in your own words, only in this way is your own thing.
Just as you see someone swim a hundred times, you can't learn it without trying.
Watch the teacher explain a hundred times, don't think about it yourself, and still stare dryly when you solve the problem yourself.

Observe more physical phenomena in life, analyze more and experience more, cultivate interest in physics, and learn well only if you are interested.

There are only a few formulas for gravitation, and you can understand them, and you can use them freely by memorizing some special situations. The most important thing in physics is the mind, and it is very important to cultivate the mind of physics, the key is to understand various theories, phenomena, and if you want to learn the stick, mathematics is also good.

Hehe, I scored 119 points in physics in the college entrance examination (when the full score was 120). More than ten years have passed, and I don't know if my experience can help you.
The experience sentence I have always enshrined is "small test and small play, big test big play" hehe.
Here's how I learned physics when I was studying it:
1. Listen carefully in class. It seems like everyone would say that. At that time, when I listened to physics class, I would enter a state of self-forgetfulness, no matter how things around me were changing, my eyes never left the teacher, and my ears did not miss a word of the teacher's lecture.
When the teacher redoes the same problem one day after a week, I will find that the same position on the blackboard will appear in the same position as the problem solving process and pictures that the teacher wrote a week ago.
It is enough to be able to listen carefully to this level. Hehe, I'm not bragging.
If the absorption rate in the classroom is close to 95% or more, then there is no need to worry about not being able to remember formulas and concepts.
2. After the teacher finishes the content of a lesson, in the time to solve problems or read books for students, I will first look up and read the teacher's board book carefully from beginning to end, then you will be surprised to find that the key points and difficulties in the content of today's teacher have been formed in your heart unconsciously. Then do the questions or read the book.
3. The homework should be completed in 10 minutes after class, and if it is not finished, it should be done before going home that day, and then ask the questions that you don't understand clearly on the day and solve it. Then go home and read the textbook again (required), and then do the physics homework (buy a reference book for yourself).
When you see a question in a reference book or in class that makes you confused, please take out your notebook and write it down carefully, and every time you have time, flip through it and take a look, which will make you gain another kind of knowledge that has never been taught, and will also reduce the probability that you will always make the same mistakes.
4. Preview the content of the next section in advance and want to be consistent with what you have learned so far. This can be quite helpful in your uptake rate in the classroom.
5. Before the exam, you don't have to worry about the physics exam, and it's OK to review other liberal arts subjects.
6. Forgot to say such an important point. After the end of each unit, you must sort out the knowledge structure of this chapter, draw a "knowledge structure tree" in your own notebook, draw the general knowledge branches, and divide a lot of specific knowledge points in each knowledge point. Then you form a complete and complete body of knowledge.
Finally, I added that the above is not mixed with any fiction, and it is my most authentic way of learning. Hope it helps.

I'm also struggling with this problem, I'm really not good at physics. But in fact, to be honest, it's still a matter of listening to class and writing homework by yourself, and if you don't understand, ask the teacher. That's what our physics teacher said... But I really can't listen to the class!!
Displacement image: The corresponding displacement at any time can be known, and the velocity can be determined according to the image, if it is an inclined straight line, the velocity can be found according to its slope, and the straight line parallel to the time axis indicates that the rest is. >>>More
1. Learn mathematics well, mathematics is the language of physics. >>>More
I am a sophomore in high school this year, and I once took the first place in physics in the experimental class >>>More
There are two situations in which an object is stationary: 1 It is not subjected to force, 2 It is balanced by force, for example, if you hold a rod in your hand and move it horizontally, the rod is in motion, but it is subjected to static friction that is vertically upward, so that it does not fall. >>>More
Never do it in physics by looking at the answers while doing the questions, which will not hurt you in the short term, but your grades will definitely be bad in the long run, because the questions will not leave much impression on your mind. The most important thing in learning physics is to think, to think about the physical model, to understand every process, only this can have twice the result with half the effort.
