Physics is very entertaining and by no meanssimple item. Studying the basic principles of this natural science, we learn how everything is arranged around. In order to master the laws of physics, besides their study and a large heap of formulas, one needs the ability to solve problems — to put knowledge into practice and show the ability to use them. But most of the students do not achieve this goal. What is the catch? The main mistake of most schoolchildren is in the wrong approaches to the solution. After all, it often happens that you seem to know what the subject of the condition is, the basic laws and formulas, and the solution does not add up.
There are special algorithms, techniques and techniques that need to be used to correctly solve problems. begins with the correct design conditions.
Для начала нужно очень внимательно изучить саму task, if there is a need, then you can re-read the condition and more than once. It is necessary to establish the main theme and the physical processes of the problem. Properly written condition - this is half the work, so do not neglect it. All physical quantities should be written in letters, and their value - a number. You need to be careful, because often the data in the conditions are not a number, but a word. For example, the boiling point of water, and we know that it is equal to 1000C. Do not forget about the units of measurement, be sure to record them in your records. As a rule, most of the problems are solved in the SI system; therefore, you need to transfer the values you received to this system. You may also need reference data for the decision, which you didn’t suspect at first (density, boiling point, etc.).
After recording all the data and competent designconditions, you need to decide on what you need to find in the task and correctly designate this value. Some tasks are simply impossible to solve without a drawing or a drawing. If, reading a condition, you can depict processes graphically, then do not be lazy and be sure to do it. Such a move can be your “lifeline”, and, at first glance, not understandable things with visual perception will seem very, very simple.
To start the solution itself, you need towrite the desired formula. You can solve problems by actions, or in general terms (print one general formula and write the solution). To whom it is convenient. If after recording the conditions you do not know where to start, then try to solve the puzzle from the end.
After solving, be sure to check the answer. First, look at the consistency of the final result - does your mosquito fly at the speed of light and does the planet weigh less than a gram?
