Título: A integração entre atividades experimentais e simulações computacionais para o ensino da física: levantamento de teses e dissertações nacionais no período de 2009 a 2019
Abstract: The present study is characterized as a bibliographic research, with a view to conducting a survey of scientific productions on the integration of experimental activities and computer simulations for the teaching of Physics. For this, the works deposited in the thesis and dissertation bank of the Coordination for the Improvement of Higher Education Personnel (CAPES), in the period from 2009 to 2019, were analyzed. Resulting in a corpus of 25 (twenty-five) productions, being 03 (three) theses and 22 (twenty-two) dissertations. It was evaluated that it is relevant to rethink the role of experimentation and simulation in education and to look for ways to concretize its potential in meaningful learning. Because, these environments are favorable to discussions of physical models, being relevant allies in the construction of concepts by students, at their different levels of education.0028-08-13T00:00:00ZA aplicação do microcontrolador ESP32 no ensino: medindo posições em função do tempo utilizando o sensor VL53L0X associado ao ESP32

Título: A aplicação do microcontrolador ESP32 no ensino: medindo posições em função do tempo utilizando o sensor VL53L0X associado ao ESP32
Abstract: The daily life of students is full of technologies and in them there is an infinity of concepts and applications of Physics. The intention when introducing the ESP32 micro controller in teaching is to provoke curiosity in students and awaken the investigative character necessary for the study of Physics, while dealing with technological elements that are part of their contemporary culture. The developed activity allows the investigation and allows the student a more active participation in their learning process, providing a conceptual growth and showing signs of a significant learning. Therefore, the work aims to show the application of the ESP32 microcontroller in teaching Physics students and related areas. For this, it was necessary to research and obtain previous knowledge about the ESP32 microcontroller and the VL53L0X position measurement sensor, in order to handle and control them correctly.0031-12-12T00:00:00ZExperimento didático com a braquistócrona e outras curvas

Título: Experimento didático com a braquistócrona e outras curvas
Abstract: In this work, a didactic experiment suitable for high school students will be built,
introducing the content in such a way that its curiosity is instigated with methodological
guidelines capable of making learning more pleasant and interactive. In this
experiment we will build: a ramp in the shape of a line, a parabola and a
brachistochrone. The objective is to show which of the trajectories traveled by two
furniture, marble and one polished block, in the vertical plane, achieves the shortest
possible time between two pre-fixed points and by the action of local gravity. The
theoretical basis behind minimizing the time on a particle trajectory between two points
in the vertical plane is the variational calculation and the Fermat principle, from which
the Euler-Lagrange equations of motion are obtained, which is equivalent to the
equations of motion Newton. For our specific case, the solutions of the Euler-Lagrange
equations show that the path (curve) that minimizes the particle travel time turns out to
be an inverted cycloid curve, which in this case is called brachistochrone. The
trajectory of a particle is called brachistochrone, which is subjected to a constant
gravitational field, without friction, with zero initial velocity and each time it rolls along
the path it changes its final velocity. We intend, with the elaboration of this thesis, to
show that the study of curves and their properties such as their speed and time is
relevant in basic education. We believe that it can be presented as curiosity and
analysis by students.0020-06-12T00:00:00ZEstudo da dinâmica de uma partícula submetida a forças resistivas do tipo linear e quadrática

Título: Estudo da dinâmica de uma partícula submetida a forças resistivas do tipo linear e quadrática
Abstract: In this Conclusion work of a specialization course in physics teaching, we analyze some aspects of the dynamics of the movement of a projectile in the vertical plane and short distance, considering that it interacts with two types of forces, the gravitational force, which is vertical and conservative and another that is due to the interaction of the projectile with the air particles (atmosphere) which results in a frictional force of dissipative nature. In the latter case we still consider the two forms of frictional force, one that is linearly proportional to the instantaneous velocity vector of the projectile and the other form where the frictional force is quadratically proportional to the vector of the instantaneous velocity of the projectile. In particular, we analyze how the projectile's mechanical energy dissipates in different parameters of the initial firing conditions, firing angle and initial velocity, in each case of the dissipative forms of the frictional forces.0012-09-10T00:00:00Z
