    • Análisis de un oscilador no lineal utilizando el método de Euler en una planilla de cálculo 

      Suárez, Álvaro; Tornaría, Fernando; ANEP CFE Instituto de profesores "Artigas" Departamento de Física; ANPE CES (Sociedad Mexicana de Física, 2019-07-01)
      Se analizan teórica y experimentalmente las oscilaciones unidimensionales no lineales de un imán que está unido a un resorte e interactúa con un grupo de imanes. Se resuelve numéricamente la ecuación de movimiento del ...

    • El campo magnético de una carga en movimiento como ejemplo didáctico de aplicación de la corriente de desplazamiento 

      Suárez, Álvaro; Departamento de Física, Instituto de Profesores Artigas (Latin American Physics Education Network, 2013-03)
      En este artículo se deduce la expresión del campo magnético generado por una partícula cargada en movimiento a partir de la ley de Ampère-Maxwell, demostrándose que dicho campo se puede modelar como generado por una ...

    • Electromagnetic field presented in introductory physics textbooks and consequences for its teaching 

      Suárez, Álvaro; Martí, Arturo C.; Zuza, Kristina; Guisasola, Jenaro; CFE; UdelaR; University of the Basque Country (UPV/EHU); University of the Basque Country (UPV/EHU) (American Physical Society, 2023-08-17)
      Textbooks play a fundamental role in teaching and learning in school science classrooms. In this paper, we investigate the presentation of the nature of the electromagnetic field in a dozen of the world’s most popular ...

    • How far away is infinity? An electromagnetics exercise to develop intuition regarding models 

      Suárez, Álvaro; Monteiro, Martín; Dutra, Mateo; Martí, Arturo C; ANEP CFE; Universidad ORT Uruguay; UdelaR; UdelaR (IOP Publishing, 2021-06-07)
      The estimation of the electric field in simple situations provides an opportunity to develop intuition about the models used in physics. We propose an activity aimed at university students where the electric field of a ...

    • Learning difficulties among students when applying Ampére-Maxwell’s law and its implications for teaching 

      Suárez, Álvaro; Martí, Arturo C.; Zuza, Kristina; Guisasola, Jenaro; CFE; UdelaR; University of the Basque Country (UPV/EHU); University of the Basque Country (UPV/EHU) (American Physical Society, 2024)
      We investigate learning difficulties among second-year students in electromagnetism courses when they apply Amp`ere-Maxwell’s law. Using phenomenography, we analyzed written answers from 65 undergraduate physics students ...

    • Normal coordinates in a system of coupled oscillators and influence of the masses of the springs 

      Suárez, Álvaro; Baccino, Daniel; Monteiro, Martín; Martí, Arturo C; ANEP CFE Instituto de profesores "Artigas"; ANEP CFE Instituto de profesores "Artigas"; Universidad ORT Uruguay; UdelaR Instituto de Física (Cornell University, 2020-07-02)
      Experimental analysis of the motion in a system of two coupled oscillators with arbitrary initial conditions was performed and the normal coordinates were obtained directly. The system consisted of two gliders moving on ...

    • Students’ conceptual difficulties in hydrodynamics 

      Suárez, Álvaro; Kahan, Sandra; Zavala, Genaro; Martí, Arturo C; ANEP CES; UdelaR Facultad de ingeniería. Instituto de Física; Escuela de Ingeniería y Ciencias, Tecnológico de Monterrey, MX; UdelaR. Facultad de Ciencias .Instituto de Física (American Physical Society, 2017)
      We describe a study on the conceptual difficulties faced by college students in understanding hydrodynamics of ideal fluids. This study was based on responses obtained in hundreds of written exams complemented with several ...

    • Unified Approach to The Electromagnetic Field: The Role of Sources, Causality and Wave Propagation 

      Suárez, Álvaro; Martí, Arturo C.; Zuza, Kristina; Guisasola, Jenaro; CFE; UdelaR; University of the Basque Country (UPV/EHU); University of the Basque Country (UPV/EHU) (Pupil Education, 2023-05)
      The question of the sources of electric and magnetic fields and their causes has been discussed extensively in the literature over the last decades. In this article, we approach this problem from the unified treatment of ...

    • Video-based analysis of the transition from slipping to rolling 

      Suárez, Álvaro; Baccino, Daniel; Martí, Arturo C; CFE; CFE; UdelaR (Cornell University, 2019)
      The problem of a disc or cylinder initially rolling with slipping on a surface and subsequently transitioning to rolling without slipping is often cited in textbooks [1-2]. Students struggle to qualitatively understand ...

    • Volviendo a las raíces: cómo crear fotos estroboscópicas a partir de vídeos digitales 

      Baccino, Daniel; Suárez, Álvaro; Martí, Arturo C; CFE; CFE; UdelaR (Cornell University, 2019)
      Mostramos aquí cómo crear a partir de filmaciones digitales usando el conocido software Tracker fotos estroboscópicas con el objetivo de analizar distintos tipos de movimientos. La ventaja de este procedimiento es que ...

    • When the Quarter Jumps into a Cup (and When It Does Not)
