SOLVING PHYSICS PROBLEMS USING DIMENSIONAL ANALYSIS

Abstract

There are many different types of ways of solving physics problems. All of them have certain features. The successful solution of a particular problem in physics largely depends on the correct choice of the applied method for this task. In this paper, one of such methods is proposed, a method of analyzing the dimensions of physical quantities, which can help students solve some physical problems. The essence of the method is that when solving the problem, if it is previously known what physical quantities are involved in the process under study, it is possible to establish the nature of the dimension that relates these quantities by comparing the dimensions. The method is very fruitful in those cases where finding the desired pattern directly meets significant mathematical difficulties or requires knowledge of such process details that are not known in advance. For a deeper understanding of the method, we presented four examples of solving problems that can be found in physics textbooks.
