Probleme de limită și extremă la fizică

Abstract

This article is about the problem-solving activity in practical lessons in the general physics course. Boundary and extreme problems were chosen. In such problems, it is proposed to compare the values of physical quantities, to arrange them in order of increase, to find out the limits of variation of the values of a physical quantity, to establish the optimal conditions for carrying out certain processes. Some problems of this kind are accompanied by diagrams or graphs. From diagrams and graphs, you can make the necessary conclusions for solving problems, you can find out the values of some physical quantities. Such problems develop the skills of building the necessary schemes, working with graphs and reading the necessary information from them. And the problem-solving activity is absolutely necessary for the formation of a good physics teacher.
