The aim of the experiment is to put online some practical work on the double pendulum by highlighting the chaotic aspect of this system. Then, we experimentally compare the ideal case with the real case (Effect of frictions) and we study the evolution of the system by changing the initial conditions. After having chosen the initial conditions, the learner launches the double pendulum, via the web. Thanks to a fast camera, she/he recovers the video showing the evolution of the system. Then, using a specific pointing software, the positions of the both masses of the double pendulum are detected over time, which allows to compare the real case with the theoretical case (without friction) and therefore to see the friction effect. The purpose of this paper is to carry out remote physics experiments for students to handle and control in real time. The experiment adopted for this work is the double pendulum. It consists of a pendulum attached to the end of another pendulum. The assembly is then set in motion from a configuration, determined by the initial conditions. To conduct this experiment remotely, we proceeded as follows: First of all, the mechanical part, in which we made the 3D design and the simulation using Solidworks in order to validate the design, then, we chose the electronic components that are compatible with the mechanical part. Finally, the IT part for the on-line setting. [ABSTRACT FROM AUTHOR] more...
