physics - it's very entertaining and not a simple thing.By studying the basic principles of natural science, of know how things work around.In order to master the laws of physics, but the most of their study and a large pile of formulas, you need the ability to solve problems - to apply knowledge in practice and show the ability to use them.But most of the students did not reach this goal.What's the catch?The main mistake most students - in the wrong approach to a solution.After all, it often happens that like you know what is involved in providing the basic laws and formulas, and the decision not all add up.
There are special algorithms, techniques and methodologies to be used here in order to solve problems.Meeting the challenges of the physics of any complexity begins with proper design conditions.
First you need to consider very carefully the task itself, if there is a need, then the condition can be read more than once.It is necessary to establish the basic theme of the physical processes and tasks.Smartly written condition - it is half the work, so do not neglect it.All physical quantities write letter designations, and their value - number.You have to be careful, because often in these conditions are not given a number and a word.For example, the boiling point of water, and we know that it is equal to 1000C.Do not forget about the units, be sure to enter them in their records.As a rule, most of the problems addressed in the SI system, because you need to transfer data quantity in the system.Also for the decision may be necessary background data, as in the beginning you did not know (the density, boiling point, etc.).
After recording all data and competent processing conditions, you need to decide what you need to find the problem and correct indicate this value.Some problems can not be solved without a picture or drawing.If the reading condition, you can graphically depict the process, do not be lazy and be sure to do it.Such a move could be your "lifeline" and, at first glance, things are not clear in the visual perception seem very, very simple.
To start the decision itself is required to write the desired formula.Solve puzzles can be on actions or in general (bring a common formula and write the solution).Whatever you like.If the recording conditions, you do not know where to start, try to solve the puzzle at the end.
After the decision be sure to check back.To begin with a look at the logical end result - not whether your mosquito flying at the speed of light and does not weigh whether the planet is less than a gram?
