High school physics is very slow, and I don t have a clue how to solve it.

How to review the 2015 college entrance examination has always been a topic of concern for candidates, and the college entrance examination channel has sorted out the 2015 college entrance examination physics answering skills, hoping to provide services for candidates. The following is an explanation of the college entrance examination review strategy.

The characteristic of the analytical method is to start from the quantity to be found, to trace the expression of each quantity in the formula to be sought (of course, in combination with the known quantity given by the question), until the unknown quantity is found. Such a way of thinking is "goal-oriented" and is a good way to be proficient.

The comprehensive method is the thinking of "integrating parts into a whole".

The method is to clarify the relationship between the parts (simple parts) and integrate the parts together to obtain a solution as a whole.

The characteristic of the synthesis method is that it starts with the known quantities and synthesizes the quantities related to each known quantity (which is searched according to the conditions given in the question).

In fact, the "analytical method" and the "synthesis method" are inseparable, the purpose of analysis is synthesis, synthesis should be based on analysis, and the two complement each other.

There are certain steps that should be followed to answer physics questions correctly.

Step 1: Understand the question. The so-called comprehension question refers to whether the phenomenon described in the question is understood.

It's impossible not to understand, what is not understanding? What's the key point you don't understand? This requires concentrating on the "difficult points" and paying attention to the "hidden conditions."

It is necessary to develop such a habit: if you don't understand the problem, don't solve the problem by hand.

If the phenomenon involved in the exercise is complex, there are many objects, there are many rules to be used, and the relationship is complex and hidden, then the exercise should be "broken into parts", and the exercise should be divided into several processes, and each process should be analyzed.

Step 2: On the basis of understanding the problem, write down the rules that should be followed in each process, and then solve the equations composed of each process.

Step 3: Discuss the answers to the exercises. Discussion can not only test whether the answer is reasonable, but also enable the reader to gain further understanding and expand the scope of knowledge.

Normally I don't do it.

First of all, we need to change our way of thinking at this time, because we all know that high school physics is changed through the way of thinking, and many times we have to connect the knowledge of junior high school so that we can learn high school physics well.

I think you must learn the basic theories well, so that you can learn physics well, in fact, as long as you lay a solid foundation, step by step is not particularly difficult.

1. Calm down and be calm can study better. 2. Attentively, there will be a breakthrough in attentive research. 3. Increase the study time, there is a difference in learning ability, but increasing the study time is the right way.

If you don't have a clue, it means that you don't really want to do the topic, you usually have to remember the content of the book clearly, and if you don't understand, you can ask your classmates, don't be embarrassed. If you don't understand a topic and don't understand it, it will accumulate more and more. It's not about the skin, it's about your grades, your understanding of physics.

From the inscription: in a considerable time t, the power transports n small cargo boxes, and the distance between adjacent small cargo boxes is l, so it can be considered that in t time, the length of the conveyor belt is nl, then the speed of the conveyor belt: v=nl t

Therefore, the speed of the small cargo box is also: v=nl t

Therefore, the work done by the motor in time t is: W=Mngh+Mn(NL) 2 2So: P=W T=mngh T+Mnt(NL) 2 2
