Uso do software Tracker para estudo e ensino da cinemática no contexto no mini cânion na cidade de Paquetá-PI

Abstract

The present work broaches the use of Information Technologies and Communication (ICTs) for the teaching of Physics as a tool to facilitate teaching and learning, and among the numerous tools available, we indicate the Tracker video analysis software for the study of Kinematics in the first year of High School with the objective of broach free fall, vertical shy, horizontal shy and oblique shy considering the air resistance force through graphs that show the characteristics of the trajectory, speed and time of a body launched under these conditions, making the study and comparison of the results with the bibliographic references that treat of the topic, the approach of the content considering the resistive forces through the use of equations become it more difficult for this level of teaching by the use of calculations at a higher level. For this, launches with sports, basketball, football and tennis balls were filmed in the mini canyon of the Sucavão stream in the city of Paquetá do Piauí to be inserted in the software and to accomplish analysis of the videos to obtain the unknown variables, such as speed, time and the characteristic of the trajectory of sports balls. The choice of location as a background to accomplish out the experiment was due to the historical context that Sucavão has for neighboring regions. In addition, a research was carried out to obtain the value of the depth of the mini canyon that according to the residents has no end, for this purpose as well as to measure the canyon wall used as a reference in the filming, a device that made it possible to better obtain the measurements. Finally, a lecture was given to the students of the first period of Physics at the Institute Federal campus Picos as a pedagogical artifact to discuss this work and the importance of scientific research
