(1218) APPLICATION OF SMARTPHONES AS TEACHING AIDS IN PHYSICS IN UNDERGRADUATE FIRST YEAR COURSES

摘要

In this paper, smartphones are presented as alternative equipment for quantitative measuring in homeexperiments, which provide support to Physics education in first year undergraduate courses. Inparticular, some quantitative applications regarding the accelerometers of smartphones are going tobe discussed.The developed projects include topics such as normal acceleration measurements of uniform circularmovement, acceleration measurements of pendulum oscillations, or the study of the law betweenacceleration and displacement in linear oscillations.The use of smartphones in physics education has definite benefits. Besides being a measurementsystem with acceptable precision, students are very intrigued and attracted to the idea of usingsmartphones in the laboratory, discovering the different sensors and possibilities of these devices forthe first time. Therefore, A magnitudes are related to practical quantitative procedures, whichare very interesting to first year technical students, who are eager to learn about the technologicalfundamentals of their specialization area.On the other hand, the measurement equipment configuration allows go more deeply into somenotions, usually approached in an A way, such as inertial forces and their dependence on themeasurement equipment configuration. In particular, with pendulum oscillations, students cancompare the different results obtained when the smartphone rotates, or when it follows a circulartransfer movement. The results show the possibilities of this approach, and its advantages whenintroducing practical projects in undergraduate Physics education.
