Research on methods to solve some types of problems in calculating errors in measurement

Abstract

Physics is an experimental science. Physical laws are often established and tested by collecting and comparing experimental data. In experiments, to determine the value of a physical quantity, we need to measure many times and there are errors. Therefore, the theory and practice of calculating errors are included in the curriculum. In the process of doing exercises to calculate errors, students often encounter difficulties and cannot apply the theoretical knowledge they have learned to the exercises. With the desire to help students absorb and self-study more easily, after each lesson, I often give a general method of solving exercises. In the scope of this article, I introduce the method of solving exercises to find errors in measurement in general physics.
