Motion study in interactive remote experiments with data collection and transfer across internet

Within the strategy of Integrated e-Learning (INTe-L) we set up several remote interactive mechanics experiments across the Internet studying the linear and curvilinear motion For the purpose, we use the measuring hardware and software -Intelligent School Experimental System (ISES) with sensing units for data collection, recording and evaluation and the software ISES WEB CONTROL kit for establishing the server-client connection. As the first experiment we devised and constructed a new and sophisticated experiment free fall, based on the motion of the permanent magnet in a glass tube with induction pick up coils for position measurement (http://remotelab4.truni.sk) To transform the hands-on experiment into a remote one, we have had to move the magnets to their starting position by the magnetic vessel, surrounding the tube. Second experiment, the mathematical pendulum remote experiment (http://remotelab5.truni.sk) was created with a unique reconstruction of its instantaneous angle of deflection using two force-sensing elements and an on-line exploited algorithm (ISES supported) for the angle of deflection on line display.
