A few important points to know about high school physics

What about high school physics? What are some good ways to study?

Now there are many friends, all say that for high school physics is a relatively difficult subject, which makes physics a kind of sore in the hearts of many high school students, in fact, learning high school physics is also very simple, as long as you master good ideas, cultivate your own study habits, let yourself like this subject, in fact, it is relatively simple.

High School Physics Textbook.

1. Learn more, observe more, and think more.

In fact, high school physics is about some theorems of things in nature, these are many things around us that contain these truths, there is physics everywhere in life, for example, every time we take a car, we can see the outside world and the things outside these cars are going backwards, this is the reference in our high school physics, this knowledge point, there is knowledge everywhere in life, you have to experience it with your heart.

As long as we have an eye for discovery, you must look more at the many phenomena in your life, whether it is natural or life, you also have to look at the stars at night, see their changes, you will also find light and heat in physics and some law problems. This knowledge is still present in our lives.

1. Learn to start with theorems.

You have to attach great importance to some theorems and some dead concepts and some laws, but you not only have to remember this knowledge from time to time, you have to learn how to use it, this is the key, smart children are using these formulas and then applying them to their own mistakes, from which to find the problem, you also have to do from a small mistake, you can review a lot of knowledge, it is really a double harvest, which is also the key to whether students can open up in high school physics.

Second, change the incomprehension to be very proficient.

Because there are many new concepts in high school physics, and there are also some nouns such as: potential energy, elastic potential energy, etc., you don't see these words that you haven't seen, and you don't like them, you know? As long as you have a deep understanding and look carefully, and then you look at some textbooks and some tutorial books, you can understand.

For learning, if you like this subject more, the better you will learn, maybe for various reasons to make you like this subject, maybe because of the teacher, some teachers grasp it tightly, you learn this subject very well, but some students just like this teacher and like this subject, if you change the teacher, you will not learn well, in fact, this is harmful to yourself.

High School Physics Exam Papers.

Read every textbook, read every unit, learn every problem, have key insights and solutions for every exercise in high school physics, maybe they use the same knowledge, as long as you remember a theorem you can do many similar problems.

1.Half-life: The time it takes for half of the nuclei of radioactive elements to decay.

2.Fission: U+(. 36)kr+3(

3.Fusion: (

4.Mass-energy equation e mc 2

Used for nuclear energy calculations.

5。Photoelectric effect: the phenomenon that metals can emit electrons under the irradiation of light e=hv h=6. Refractive index: n=c v

7。Red light has the longest wavelength and violet light is the shortest.

7.It's too difficult to graph.

High School Physics 1Kinematics: The study of the basic concepts and laws of motion such as the state of motion, velocity, acceleration, and displacement of objects, such as uniform linear motion, accelerated linear motion, free fall, etc.

2.Mechanics: The study of the relationship between the force, mass, and acceleration of an object, as well as the concepts and principles related to mechanics such as the movement, impulse, and conservation of momentum of an object in the case of equilibrium and imbalance of forces

The study of energy-related concepts and principles such as kinetic energy, potential energy, conservation law of mechanical energy, work, power, etc. of an object.

5.Thermal: the study of heat, heat, gas equation of state and other heat-related concepts and principles of objects: the study of optical principles and phenomena such as propagation, reflection, refraction, wave and particle nature of light, and image of light.

7.Electricity: the study of electric charge, electric field, potential difference, analysis of electrical circuits, etc.

Acoustics: The concept and principle of sound waves and sound transmission are the main contents of high school physics.
