Survey of the Evolution of Two Points Belonging to Two Objects Falling withoutInitial Speed Dynamic Chart (Dot per Dot) Video (Frame by Frame) Coupling

Michel Calmet

Résumé

This paper presents one experiment on a computer screen with a " dynamic chart " linked to a " video footage ". As the user can shift dots in the chart simultaneously with the video footage playing frame by frame, this applicationis named: " chart-video coupling " .Used in a physics experiment concerning gravity, this paper focuses on a possibility to model and to simulate in specific cases, when objects fall, one part of these objects can fall faster or slower than their centers of mass. This chart-video coupling was first elaborated for sport science students at the University of Montpellier. The use and the elaboration of this application about video motion analysis concern athletes, sports coaches, medical doctors and students. To train thesein " ICT and sports " , a course is organized at the faculty of sportscience at the University of Montpellier. Students have to choose and to build 4 applications among 5. Theseapplications are consistent with the certificates concerning computer sciences and Internet delivered by French Ministry of Higher Education and Research.These applications allow both training and research and put in evidence some events that human eyes cannot see easily. Satisfaction surveyshave shown that students found this course adapted to their curriculum andit helps them to understand how professional softwareruns. Since 2007, applications havebeen updated and upgraded, and used by 6 teachers each year. They allowed 3 publications in sports totaling 92 quotes. These applications allowinterdisciplinary approaches between ICT and physics.Examples were built about gravity, Newton's pendulum, and juggling. The oneconcerning gravity was used in adult education within Algerian universities. Perspectives are to build 3 dimensional graphs with two cameras and to integrate new applications on smartphone (accelerometers, gyroscopes).
