APPLICATION OF INFORMATION TECHNOLOGIES FOR CONSTRUCTION AND ANALYSIS OF GRAPHS IN THE PROCESS OF STUDY OF GENERAL PHYSICS COURSE

Abstract

The article considers the method of using information technology tools for the construction and analysis of graphs in the process of studying the course of general physics. Among the significant number of computer tools for plotting functions, special attention is paid to software that allows to process laboratory tasks results in physics effectively and graphically, to perform calculations and build on their basis graphs of dependencies while solving tasks, to demonstrate models of physical phenomena on lectures. Using the example of laboratory work on the capacitance of the capacitor determination, it is shown that as a result of using the software Graph for processing experimental data reduces the time of their processing and the error of the calculation results. The construction of function graphs of the studied quantities also contributes to a fuller understanding of the physical process, which is considered in the task. The method of using the graphical capabilities of the Excel spreadsheet and plotting functions based on the analytical solution of the problem are considered. The construction of dependency graphs of physical quantities in real time is considered exemplified by oscillations of a mathematical pendulum, which are modeled using SimPHY software. Real-time graphs can be built by processing physical sensor data of various types using the Arduino hardware computing platform and SFMonitor software. Carrying out laboratory work in this way makes it possible to conduct a real physical experiment simultaneously with the display of its results on the screen, to observe the relationship between specific changes made to the conditions of the experiment and their graphical display. The use of 3D graphs is considered as in the case of visualization of three-dimensional vector fields in Matlab: force lines of electric and dipole field strength and potential of electric dipole field. For 3D graphics, the use of height and color gradients significantly increases the visibility of images. Graphic method in combination with information technology has a very high potential in the implementation of the main objectives of teaching physics.
