Can anyone provide me with a complete set of high school physics and electricity teaching content?

As a high school physics teacher who has been teaching for 15 years, I would like to give some advice to my students. We will discuss the specific suggestions on a case-by-case basis.

For the electricity part, high school students can do some experiments. Such an experiment can give you the best results. When you go to the problem again, you can find that everything has been solved.

The best way is to learn through practice, so that you can get twice the result with half the effort, you can better experience the knowledge, learn more solidly, and buy some equipment to do it yourself.

Deeply understand the formula by heart, and apply it skillfully. The relevant data found in the reading question, set the formula, and calculate the unknown quantity. Observe life and understand the physical and electrical part.

In fact, the high school physics and electricity part still mainly depends on understanding, and to memorize the corresponding formulas, you have to brush up on more questions.

High school physics and electricity may seem difficult to understand, but different mechanics can be intuitively felt and imagined, and the large version of electricity needs to be structured, understood, and analyzed in the brain. But when you really understand it, there is no difficulty. The first thing you will learn is the concept of electric field, which is the most fictional.

However, it can be understood in connection with the gravitational field, and the concept of "potential" can be understood well, and the image of the electric field line and the equipotential surface can be basically solved, and the most important thing is to follow a good teacher. After that, you will learn the circuit, different from junior high school, the power supply in high school is basically no longer "ideal", the concept of internal resistance should enter the mind, and what you learn in junior high school should be linked, the characteristics of parallel series circuits must be marked, in general, the review of junior high school knowledge is very necessary, and then the use of formulas in various types of questions. Your teacher should give different questions to practice, pay attention to understand each of the questions in the practice, after doing a few questions can be deduced into a variety of topics, you will find that electricity is actually only those few ideas, compared to electromagnetism and other electricity is relatively simple.

In general, go with a good teacher and review the basics of electricity in junior high school, and everything will be fine.

Learning progress.

When I first came into contact with high school electricity, I felt pressure, but in fact, I didn't have to, and I was back in junior high school.

Knowledge must be reviewed, do not answer the electrical part of high school just learned is the electric field, some concepts are more abstract, the key is to correctly understand the concepts and laws, do not rush, when doing the problem with the basic knowledge points of the textbook, knowledge is accumulated little by little. May you learn and progress!

Running through the beginning and end is Ohm's law for all circuits.

Since so easy

This part is super simple, and it's good to know how to look at the big picture and think about the big picture, and pay attention to the equivalent changes in the circuit.

Don't be too rigid, what external circuits, internal circuits, are all nonsense, it's all electronic components, they can be power supplies, they can be resistors.

In a word: Ohm's law is used up!

There is no need to review junior high school.

Ohm's law of the whole circuit should be skillfully used, which is the most basic The topic is changing, but it is all around this law, and the problem must be transformed when you see it, that is, the equivalent change. I won't go into more detail about some specific tips.

Why don't you read the textbook?

Knowing the direction of gravity and the direction of motion, make a triangle, g is the hypotenuse so the electric field force is the minimum, and do the perpendicular line in the direction of motion, so e is the minimum (root number 2 2*mg) q

Direction; Direction of vertical movement.

mg q vertically upwards Since the particles move in a uniform linear velocity, the resultant external force on the particles is zero, and the particles are only affected by gravity and the electric field force, so the gravity is equal to the electric field force, and the direction is opposite, so e=mg q, and because the gravity force is vertically downward, the electric field force is vertically upward!

Upstairs, you are wrong, the electric field force is perpendicular to the direction of velocity, the magnitude is [mg cos45 degrees], the particles are moving in a straight line, and it is not said to be moving in a straight line at a uniform speed!
