There are a lot of physics formulas in high school, how to memorize the fastest and strongest 20

Don't memorize by rote, only understand, only understand to remember! In fact, many physics formulas are derived from basic formulas, and the basic formulas of high school physics are just a few, and you must learn to be flexible and learn to deduce and understand the formulas. If you learn physics by rote memorization of formulas and models, it is impossible to make a big breakthrough!

I hope mine can be helpful to you, and I wish you happy studying!

If you don't know some formulas, you can figure it out by doing some simple questions, and you won't find it difficult. The most important thing is to improve your confidence in it. Don't do too difficult questions at first.

Don't memorize those formulas, you can find a few simple problems to do, don't have a complicated process, that is, the kind of problems that can be done only with formula algebra, and memorize them after doing them a few more times.

It is necessary to understand the meaning of each formula, that is, to be able to 'translate' it in Chinese, and also to relate it to specific physical situations, so that you can remember it more firmly and be handy when answering questions. Give it a try and I wish you success!

You need to understand the meaning of each formula and then strengthen your memory by doing the questions! I wish you all the best.

In fact, most of the formulas above physics are compound formulas. Only the most basic basic formula is needed, and the rest is the understanding and derivation of the formula, and the process of deriving the formula is also the process of learning and understanding.

The explanation on the first floor is in place, with the experience of three years of high school along the way, you can memorize the formula by doing the questions, and understand and help memorization.

There's less to say, it's best to buy a small book of this formula to see, and it will be more difficult to read more!

To understand the meaning of the formula, you can make up your own tips to make it easy for you to remember.

Remember the main ones, the others can be pushed out.

Many juniors asked me.

Senior, I'm in my third year of high school now, and I can basically memorize formulas and theorems and write them silently, and the basic knowledge is not bad. I've been studying this winter vacation, why don't I still know how to do the questions?

Either I miscalculated, or I got stuck halfway through a certain step, what should I do?

First of all, you must understand that memorizing formulas ≠ knowing formulas.

Our common formulas fall into the following 4 categories:

Definition of artificiality.

Experimentally derived laws.

A theorem that is logically derived from the first two.

Secondary conclusions. When memorizing formulas, it is necessary to be clear about the circumstances and conditions under which corresponding formulas and conclusions should be used.

If you don't memorize all these things, you only know the Qinglianshan formula itself and don't know its experiment and derivation process.

Of course you won't use this formula when doing problems.

So it's not enough to just memorize formulas, so what else do students need to do?

First of all, it is necessary to know what the specific linguistic narrative of the formula is.

For example: f = ma

The standard expression on the textbook is:

The resultant external force of an object is numerically equal to the product of the mass of the object itself and the velocity of the object.

Being able to express it in accurate language is the basic condition for achieving the "knowing the formula".

Secondly, it is necessary to grasp the relationship between the question stem, the formula and the content.

Understand that the title will not tell you the formula, nor will it give you an exact theorem or law.

The only thing we can give you is the question stem, so what we need to do is to analyze the corresponding formula to be used from the question stem, and then the formula is related to the corresponding knowledge content.

Understand the problem, find the formula, and use the formula to solve the problem based on knowledge.

This is a complete and correct process for solving problems.

Therefore, you can't understand why you basically know physics formulas in high school, and you know a lot of basic knowledge, but you just can't do questions.

Actually, it's you who overestimate yourself.

I thought I could do it, but in fact, it was far from it.

What you have to do now, there are two things:

First, read the textbook. Make sure that the specific language description and expression meaning of the formula I mentioned above are well understood.

Second, the meaning of each physical quantity in the formula and the corresponding knowledge points should be written down word by word in a notebook, so don't be tired.

If you can't even do these two points, no matter how many formulas you memorize and how many questions you desperately brush, it will be useless and will only make your efforts wasted!

Don't get lost!

Summary. 1. The three formulas of gravity are: g=mg; g=g/m；m=g/g。

where g = , it represents the physical meaning that the gravitational force of an object with a mass of 1 kg is . The force exerted on an object due to the attraction of the earth is called gravity.

The direction is always straight downwards and not necessarily towards the center of the earth. The gravitational force exerted on an object at the same point on the ground is proportional to the mass m of the object.

1. The three formulas of gravity are: g=mg; g=g/m；m=g/g。where g=, it indicates that the physical meaning of potato staring is:

An object with a mass of 1kg is subjected to a weight of high maw force. The force exerted on an object due to the attraction of the earth is called gravity. The direction is always straight downwards and not necessarily towards the center of the earth.

The gravitational force of an object at the same point on the ground is proportional to the mass m of the object.

2. Sliding friction: f = fnf, if which age is static grinding with friction, n is the support force of the ground for the object, this support force is equal to the value of the force in the opposite direction of the object's support force, for example, mg = n on the plane, mg cos = n on the inclined plane, is the dynamic friction factor, effective in sliding friction, refers to the ratio of the force exerted by you to drag the object at a constant speed to the gravitational force.

3. Displacement uses displacement to represent the change in the position of the object. A directed line segment from the initial vertical position to the last position. Its size is independent of the path, and the direction is from the start point to the end point.

It is a physical quantity, i.e., a vector, with envy size and direction. The displacement difference formula is: x1=v0t+1 2at 2, v1=v0+at, x2=v1t+1 2at 2, so x2-x1=v1t-v0t=at 2, i.e. x=at.

Speed formula: v=v0+at

Displacement formula: s=v0t+1 2at2 velocity displacement formula: vt 2-v0 2=2as

Velocity at the midpoint of time: v=(v1+v2) 2

The velocity at the midpoint of displacement: v=(2v1v2) (v1+v2)= v0 2 + vt 2) 2) v1 v2 are the displacement velocity of the previous stage and the displacement velocity of the later stage, respectively.

v0 vt is the initial velocity and the final velocity, respectively.

x=at 2 (application: dot timer, etc.).

1: ...... t, 2t, 3tAt the end of the nt time, the instantaneous velocity ratio is 1:2:3 :....n

It is known that a is unchanged (uniform acceleration motion) vt=at

vt1:vt2:vt3:……vtn=a*t1:a*t2:a*t3:……a*tn=t1:t2:t3:……tn=1：2：3：……n

2: ...... t, 2t, 3tIn NT time, the ratio of displacement = 1:4:9:......n^2

Or is it known that a is constant, based on s=, derived.

s1：s2：s3：……sn=1：4：9：……n^2

3: ...... in the first, second, and third timeDisplacement ratio in the nth time.

s1':s2':s3''=1;3;5;..2n-1

Draw the picture first, a or the same, s1'=s1 ,s2'=s2-s1,s3'=s4-s3,sn'=sn-sn-1

Based on 2, it can be derived.

4: The ratio of the time taken to pass a continuous equal displacement from the beginning of the rest is.

t1：t2：t3：……tn=1: root number 2 -1: root number 3 - root number 2: .Root number n - root number n-1

All formulas are pushed, they will be pushed, and you don't have to memorize anything. For example, there are many formulas in kinematics, but it is not only difficult to memorize, but it is also difficult to figure out which one to use in the exam. What to do? Draw a V-T diagram!

All formulas of kinematics can be deduced from the V-T diagram. If you find the distance: s=vt 2 is to find the area formula of the triangle, 1 2 base times the height.

Similarly, (at 2) 2=x(displacement).

The essence is 1 2 base times high.

The landlord knows how to derive, and only needs to memorize a few of the most basic formulas that are prescribed, and many complex formulas can be introduced.

If the landlord thinks this is not good, then I have 1 way: look at the unit.

Physical operations are united, and the derivation process of formulas naturally has units. So sometimes you forget the formulas, you can start with the units and recall those formulas.

You should memorize the formulas that you need to use when doing practice problems.

Understand, deduce for yourself.

There are many formulas but there are only a few basic ones, and the others can be deduced through the basic formulas, and there is no need to deliberately memorize them, and memorizing them has no effect.

1. Remember what physical quantity the letters represent.

2. Remember the logical relationship between the physical quantities represented by these letters in physics.

3. It is best to deduce it yourself according to the definition or law.

1.Formulas are the essence of physics, and remembering formulas is the basis for solving physics problems.

2.When listening to and explaining physical formulas, we must pay attention to the derivation of the process, and the key is to understand the origin of the formula and understand the connotation and extension of the formula.

3.Write silently on a regular basis, and review carefully for those who don't know

4.Various forms are used to aid memory, for example, the displacement formula for linear motion with uniform speed is the sum of the area of the triangle and the area of the rectangle. You can draw a velocity-time image as soon as you don't.

5. Auxiliary memory methods also include: doing experiments, doing exercises, looking at example questions, writing summaries, and summarizing question types.

Hope it helps.

Remember that formulas are the foundation when doing physics problems, and modeling ability is the main thing. It's good to memorize the formula for the old question, but the new question is still more difficult to use the formula. Therefore, I suggest that only by doing more questions and finding rules in the questions is the key to learning physics well.

As for how to memorize formulas, my experience is to figure out the origin of each formula, so that you can really achieve a thorough understanding. I also took a lot of notes in class, and I took a lot of notes in physics class, whether it was college or high school. If you want to read physics well, you must not only have a smart brain, but also have diligent hands.

May you experience the joy of physics soon.

In fact, the problem of learning should be self-summarized. But since you're asking, let's talk about my method.

First of all, there is no need to talk about the basic formula, which is available in textbooks and will often be encountered when doing problems. Read the book carefully, do more questions, and you will naturally remember it.

Second, complex formulas that extend from the basic formula rely on rote memorization. The trick is to classify these formulas and try to deduce them yourself to deepen your impression. Maybe there are a lot of formulas like this, and I can't remember it at first, but it doesn't matter, the teacher will help you, and the physics test papers are flying all over the sky.

The most important thing is to have confidence in yourself, the first year of high school physics is a grade higher than the junior high school physics, in fact, it is a little more complicated, listen carefully in class, do some targeted exercises after class, physics learning is actually not difficult.

Finally, I would like to say, communicate more with the teacher, the teacher in high school should be the most memorable for us in the future.

Only by understanding can you remember better, so you have to read more books, that's the king!

Connect each trunk knowledge point into a line, and then expand the other knowledge points along the main line, and slowly you will form a knowledge network of physics...

In fact, physics is very simple, don't memorize concepts, have a big picture of the problem, and you will find that you have learned it...

Of course, you need some typical question types to foreshadow, in order to have a big breakthrough.
