    This research work has its origin in one of the current teaching problems, since it is absolutely necessary to develop new models for students to understand and interpret the lessons given by teachers, so that learning is fully understandable. For this reason, a test bench was developed to calculate the static and dynamic friction coefficient of certain materials (glass, steel, metal, wood and plastic). The development of the test bench was oriented on an experimental research methodology since its design is fully automated based on sensors (LM393, KY-008) and a PLC FX2N-16MR/T; main elements that allowed the development of an open loop system that responds to the needs of the test bench (determination of acceleration and friction coefficients). The data collection was established by means of five repetitions, which allowed to establish the most adjusted value to the data collected in specific bibliography. It is necessary to emphasize that the relative and absolute percentage of error of the values of both the bench and the bibliographic collection range from 5 to 10 percent of error.
