The EJS version allows instructors to create custom configurations for teaching. Instructors set the heights of the track segments and the model displays the position-space particle motion as well as position and velocity graphs and tables. The customized simulation is then saved with associated curricular as a new jar file that can be redistributed. http://www.compadre.org/OSP/items/detail.cfm?ID=12023 http://www.compadre.org/Repository/document/ServeFile.cfm?ID=12023&DocID=2887 http://www.compadre.org/OSP/bulletinboard/Thread.cfm?ID=12023 Wed, 30 May 2012 00:00:00 EST The Confined Hard Disk Two Piston System simulates a constant-energy two-dimensional system of unit mass particles confined by two frictionless pistons of equal mass M. This computer model was featured on the cover of the American Journal of Physics. http://www.compadre.org/OSP/items/detail.cfm?ID=10835 http://www.compadre.org/Repository/document/ServeFile.cfm?ID=10835&DocID=2188 http://www.compadre.org/OSP/bulletinboard/Thread.cfm?ID=10835 Thu, 03 Nov 2011 00:00:00 EST The STP Percolation program generates occupied lattice sites for a given probability and determines the clusters of occupied sites. This program demonstrates properties of percolation, especially near the geometric phase transition, and is part of a group of simulations for Statistical and Thermal Physics. http://www.compadre.org/OSP/items/detail.cfm?ID=8649 http://www.compadre.org/Repository/document/ServeFile.cfm?ID=8649&DocID=1062 http://www.compadre.org/OSP/bulletinboard/Thread.cfm?ID=8649 Tue, 31 Mar 2009 00:00:00 EST The Polarizer program displays the effect of a plane polarizer on an incident electromagnetic wave. The default electromagnetic wave is plane polarized but this polarization can be changed using the input fields. The slider can be used to rotate the polarizer to change its orientation. http://www.compadre.org/OSP/items/detail.cfm?ID=7178 http://www.compadre.org/Repository/document/ServeFile.cfm?ID=7178&DocID=362 http://www.compadre.org/OSP/bulletinboard/Thread.cfm?ID=7178 Sun, 06 Jul 2008 00:00:00 EST The Orbit program displays the dynamics of multiple massive objects interacting gravitationally. The default scenario shows the figure-eight orbit of three particles first discovered by Montgomery. Additional particles and their initial positions and velocities can be specified. http://www.compadre.org/OSP/items/detail.cfm?ID=7182 http://www.compadre.org/Repository/document/ServeFile.cfm?ID=7182&DocID=366 http://www.compadre.org/OSP/bulletinboard/Thread.cfm?ID=7182 Sun, 06 Jul 2008 00:00:00 EST The QM Wigner program displays the position-space wave function and the associated quasi phase space probability distribution using the Wigner function. http://www.compadre.org/OSP/items/detail.cfm?ID=6813 http://www.compadre.org/Repository/document/ServeFile.cfm?ID=6813&DocID=294 http://www.compadre.org/OSP/bulletinboard/Thread.cfm?ID=6813 Tue, 01 May 2007 00:00:00 EST
