The use of multimedia tools for the development and implementation of teaching material is considered of paramount importance for first degree courses. Thus, we have observed, in fundamentals of Physics subjects, how the use of this kind of didactic material increases the motivation and the learning curve of the student. In this work, we present a virtual lab for the calculation of moments that allow multiple selections such as the vector representation, its action line and the moment in a 3D environment. This applet allows the user modifying the point of view and the scale in an interactive way. Besides the visualization, this virtual lab allows the calculation of the moment of a sliding vector with respect to an axis and perform different operation between them. Additionally, it helps to understand the relation between the velocity at a point and the angular velocity of the rigid body in rotation to whom it belongs, the moment of a force with respect to an axis, and the way that this force affects the rotation. All of this supports the development of several transversal skills. Diseño y evaluación de un laboratorio virtual para visualizar momentos de un vector deslizante en 3D

In this work, we detail a new application of the use of the smartphone in the laboratory of Physics, in order to show the students that new technologies and the Physics' basic principles are compatible.From the set of sensors that a mid-range mobile phone has, we have chosen the microphone for this study. We have designed an experience of sound waves superposition (acoustic beat) which combines the use of the common instrumentation of a Physics laboratory, such as current generators and speakers, and the smartphone as a measuring tool.Using a simple free application designed for Android TM smartphones, one can measure the acoustic intensity as a function of time and then export registered data to a csv file format. Applying common graphic and adjustment tools, the frequency of the beat generated by the superposition of two sinusoidal acoustic waves, with equal intensity and close frequencies, can be obtained in order to check that the difference between the two frequencies matches the acoustic beat frecuency.
ResumenEn este trabajo se detalla una nueva aplicación del uso del teléfono móvil "inteligente" (smartphone) dentro del laboratorio de Física, con objeto de mostrar a los alumnos que las nuevas tecnologías y los principios básicos de la Física no son universos excluyentes.El teléfono móvil inteligente: una herramienta para el estudio de la acústica experimental
2015, Universitat Politècnica de ValènciaCongreso IN-RED (2015) De entre los diversos sensores que tiene un teléfono móvil de gama media, se ha trabajado con el micrófono. Se ha diseñado una práctica de superposición de ondas sonoras (batido acústico) en la que junto a elementos habituales de un laboratorio de Física, como son los generadores de corriente y los altavoces, se incluye el teléfono móvil como herramienta de medida.
