If you are a fool who learns physics, the key is to understand and use it. Are you a junior high school student or a high school student?
Physics in middle and high school is nothing more than force, motion, electromagnetism, and gas state changes. The focus is, of course, on force and movement; The key to this is force analysis and motion analysis. Basically, if you learn force analysis well, you will be able to master high school physics.
In fact, it is very simple: an object, first find all the forces it is subjected to, including the earth's gravity, friction, external forces, etc., and figure it out; The direction and magnitude of the force. The size is easy to judge, the direction is mainly gravity always vertical downward, friction is always parallel to the contact surface, and the rope tension is always the direction of the rope ......; After putting it all; The force is calculated in two perpendicular directions.
The relationship between motion and force is a Newton's second law, just figure it out. In fact, it's just a gravitational acceleration. As long as you understand this, other problems in physics can be easily solved.
Now it feels like physics is simple, right? If you are good at math, it means that your thinking ability is not bad and you have a foundation, so I hope you can find interest in force analysis. Good luck!

Generally good in mathematics, there are great advantages in physics, and the way of thinking is the same in many cases, and interest and confidence are the premises.
-
In fact, the correlation coefficient between mathematics and physics is not as large as that of mathematics and chemistry, so don't always think that mathematics and physics must be good, but we still need to pay attention to it. Go for it, your IQ shouldn't be a problem.
-
If you only study physics, the relationship between physics and mathematics is not large, but the more you go later, there will be a lot of integration with mathematics, if physics is not ideal at that time, it means that there is a problem with the foundation, and you should turn to the previous books.

Mathematics and physics complement each other, and the difficulty is the same when you get to university, both of which are very difficult, but if you are only in middle school, physics will be slightly more difficult.
1. First of all, mathematics is a basic subject, and the research in high school is not deep, and the question type of the college entrance examination is basically fixed every year, there is a fixed answer routine, as long as the mathematics is hard to pass 100, it is not difficult to score 120 points.
2. If everyone can pass mathematics, then everyone in physics is generally forty or fifty points, one of the reasons is that the physics multiple-choice questions in most regional exams are indefinite, which increases the difficulty, and the physics problems need to analyze the causes and consequences, resulting in the difficulty of most students to pass.
3. Students who are good at physics but not good at mathematics can only say that they are not interested in learning mathematics and do not do enough questions.
4. I have seen a lot of students who are good at mathematics and physics, most of them are students with medium grades and very hard work, and good mathematics is limited to 120 points, and it is difficult to break through.
Study advice. 1. Learn to formulate.
This includes setting learning objectives, scheduling, resource allocation, and more. Learning to make a study plan can save study time and improve learning efficiency.
2. Learn to prepare.
Ye Shengtao, an educator, said: If students are not taught to prepare, they will not be able to experience several mental processes that are very valuable in learning. Learn to prepare, and you can fight a prepared battle. Teaching students how to prepare for the lesson allows them to better participate in the classroom.
3. Learn to listen to lectures.
It is an important part of study and life, and learning to listen to lectures is the top priority of learning Fa guidance. In classroom teaching, students should listen carefully, pay attention to watching, use their brains more, practice more and memorize more, summarize and summarize, and regard themselves as the main body of learning, rather than spectators.
4. Learn to review.
Learning to review is a great way to understand and reinforce what you have learned. As the saying goes, review is the process of reprocessing knowledge concentration. Kelov said that he drove the carriage, did not look behind, only drove forward, and drove home only an empty carriage.
If you only study and don't review, you will almost forget it at the end of the semester, and many students will not do well in the exam as soon as they arrive, which has a lot to do with not being able to review.
5. Learn to write homework.
Homework writing is the process of allowing students to think independently and use what they have learned to try to solve problems. When writing assignments, we will check and verify the knowledge taught in class, and find any gaps in understanding, and if we correct them in time, we can continue to improve.

The foundation of physics is mathematics, and it is more difficult to learn mathematics well than physics.
-
Physics is a little harder to teach.
Because physics is relatively lively.
Reading is important.
Math is a little better.
-
Each has its own merits. It's easy to learn which one, thinking in different directions, but interconnected.

1. Good mathematics is not necessarily good physics, and bad mathematics is not necessarily bad physics.
2. There are many knowledge points in mathematics, and the difficulty gradient is also different, from the set to the conic curve, each knowledge point will involve different question types, of course, the difficulty is also different. Compared with physics, mathematics does not have high requirements for the knowledge system, and for example, mathematics questions often only examine a single knowledge point, for example, if the test is a number series, although sometimes it will be interspersed with other knowledge points, but often only the number series is examined. Generally speaking, the first ten multiple-choice questions and the first two multiple-choice questions in mathematics, as well as number series, solid geometry, probability questions, optional questions, and trigonometric function questions are relatively simple.
3. Physics is a relatively comprehensive subject, it is different from mathematics, it requires students to have a relatively strong knowledge system, a physics question often involves many knowledge points, although it seems difficult, but physics will involve a lot of physical models, but when you understand these models, and you can substitute the model into it in the exam, you can easily solve the physics problem, you can get a very good score. Therefore, if you are not good at mathematics, you may not be able to learn physics well.

1. It is difficult to learn physics well, and there is a certain correlation between the two.
2. Most of the junior high school students are easy to understand, and the calculation is not too complicated. The focus of this stage is to understand how to turn physical phenomena into a mathematical formula to solve, the process of solving is not difficult, and the level of determining the mathematical formula is your physical level.
3. High school physics will be a big change, and the knowledge of one-dimensional quadratic equations, code analytic geometry, and three-dimensional geometry will be more involved, and there must be an adaptation process. At this time, it is necessary to have a good foundation in mathematics.
If you are good at mathematics, physical chemistry is not far behind, and the employment prospects of science are relatively good, so it is recommended to choose science. But don't jump to conclusions right now, maybe you're a big fan of liberal arts. I used to be good at geography but went to science, so I thought it would be better to see which aspect I was more suitable for before making a decision. >>>More

I think that whether you learn mathematics or physics, you should have a good habit of pre-study before class, read a good book before class and understand that you understand that you don't understand, and then look at some extracurricular tutorial books, I mainly read the Longmen series when studying, and I feel better. Remember** is not to understand the class to bring to, because may not be nervous in forty-five minutes, at this time must remember not to slip when you can't speak, pay attention to listening, if you still don't have to learn to take the initiative to find the teacher or classmates to know to understand, remember not to be ashamed to ask. Both mathematics and physics have to start with relatively simple basic problems, in fact, the so-called difficult problems are nothing more than some simple problems connected together, and you have to learn to analyze. >>>More

This is a difficult situation to deal with, because mathematics is the most important subject in science and engineering, and English is the most developmental subject. If it is better to study machinery and electricity in middle school, the way out is also better.
