In this case, the gerbil running in its wheel and the bucket pump are the equivalent of a battery. The water represents the electrons in the circuit. The height represents the voltage. The wheel represents the resistor. As the electrons fall from high to low, energy is available to do work. http://www.compadre.org/introphys/items/detail.cfm?ID=10559 http://virlab.virginia.edu/VL/Resistor_H2O.htm http://www.compadre.org/introphys/bulletinboard/Thread.cfm?ID=10559 Thu, 23 Dec 2010 00:00:00 EST This is an interactive simulation on the topic of Nuclear Magnetic Resonance (NMR) and Magnetic Resonance Imaging (MRI). The user can change the applied magnetic field and the RF signal and observe the effect on spins. In the NMR mode, the user can choose between various from among several atoms. In the MRI mode, the user can elect to add a tumor to the head being visualized. http://www.compadre.org/introphys/items/detail.cfm?ID=6111 http://phet.colorado.edu/en/simulation/mri http://www.compadre.org/introphys/bulletinboard/Thread.cfm?ID=6111 Fri, 12 Mar 2010 00:00:00 EST This applet allows the user to make a lens or a mirror and observe its effect on distant light. The user can change the thickness, the curvatures, the diameter, the index of refraction of the lens, and the index of refraction of the surrounding medium. Several special cases are pre-programmed and can be invoked by clicking on a link. http://www.compadre.org/introphys/items/detail.cfm?ID=6152 http://www.phy.ntnu.edu.tw/ntnujava/index.php?topic=121.0 http://www.compadre.org/introphys/bulletinboard/Thread.cfm?ID=6152 Tue, 27 Jan 2009 00:00:00 EST This interactive java application allows you to investigate the properties of converging lenses. You can change the index of refraction, the diameter and the radius of curvature of the lens. You can also change the types of objects used and the types of rays shown. http://www.compadre.org/introphys/items/detail.cfm?ID=7629 http://phet.colorado.edu/en/simulation/geometric-optics http://www.compadre.org/introphys/bulletinboard/Thread.cfm?ID=7629 Sat, 27 Dec 2008 00:00:00 EST This is PhET simulation on the topic of circular motion featuring one or two ladybugs. Users can change the various initial kinematics quantities and display time progression vectors, graphs and data of these kinematics quantities. http://www.compadre.org/introphys/items/detail.cfm?ID=8239 http://phet.colorado.edu/en/simulation/rotation http://www.compadre.org/introphys/bulletinboard/Thread.cfm?ID=8239 Mon, 10 Nov 2008 00:00:00 EST This website featurs photo, video, and simulation galleries that explore the fascinating worlds of electricity and magnetism. This extensive library includes illustrated tutorials, historical facts, and applications to new technology. http://www.compadre.org/introphys/items/detail.cfm?ID=8128 http://www.magnet.fsu.edu/education/tutorials/ http://www.compadre.org/introphys/bulletinboard/Thread.cfm?ID=8128 Tue, 07 Oct 2008 00:00:00 EST This applet shows the equipotential lines and the electric field lines for a single positive or negative charge, two equal positive or negative charges, two unequal like or unlike charges, and unequal unlike charges. http://www.compadre.org/introphys/items/detail.cfm?ID=4461 http://vnatsci.ltu.edu/s_schneider/physlets/main/equipotentials.shtml http://www.compadre.org/introphys/bulletinboard/Thread.cfm?ID=4461 Sun, 07 Sep 2008 00:00:00 EST This resource provides clips from Warner Brothers Road Runner and Coyote cartoons. Suggestions for use are included next to each clip. A Microsoft PowerPoint presentation based on the clips is also provided. http://www.compadre.org/introphys/items/detail.cfm?ID=7929 http://www.lghs.net/ourpages/users/dburns/RRPhysics/Road_Runner_Physics/Movie.html http://www.compadre.org/introphys/bulletinboard/Thread.cfm?ID=7929 Tue, 02 Sep 2008 00:00:00 EST The circuit simulator applet allows the user to virtually build and a test an infinite number of circuit configurations. The picture shows a full wave rectifier setup. The user can change the frequency, the waveform, the maximum voltage, the DC offset, the phase offset, the diode forward voltage, and the load resistance. http://www.compadre.org/introphys/items/detail.cfm?ID=7620 http://www.falstad.com/circuit/ http://www.compadre.org/introphys/bulletinboard/Thread.cfm?ID=7620 Sat, 02 Aug 2008 00:00:00 EST The Polarizer program displays the effect of a plane polarizer on an incident electromagnetic wave. The polarization of the electromagnetic wave and the orientation of the polarizer can be modified. http://www.compadre.org/introphys/items/detail.cfm?ID=7178 http://www.compadre.org/Repository/document/ServeFile.cfm?ID=7178&DocID=362 http://www.compadre.org/introphys/bulletinboard/Thread.cfm?ID=7178 Thu, 10 Jul 2008 00:00:00 EST
