Baton Throw Model 

written by Wolfgang Christian and Mario Belloni

The Ejs Baton Throw model displays a baton thrown up in the air about its center of mass.  The baton is modeled by two masses separated by a massless rigid rod.  The path of the center of mass of the baton and one of the red masses are shown in black and red, respectively.  The ratio of the two masses can be set with a slider. Initial velocity of the center of mass of the baton and the rotational velocity of the baton can be set via text boxes.

To Modify this Simulation: The Ejs modeling tool may be installed by right-clicking within the plot and selecting "Open Ejs Model" from the pop-up menu item.  The simulation may then be modified by the user.

Ejs Baton Throw model was created using the Easy Java Simulations (Ejs) modeling tool.  It is distributed as a ready-to-run (compiled) Java archive.  Double clicking the ejs_mech_cm_BatonThrow.jar file will run the program if Java is installed.  Ejs is a part of the Open Source Physics Project and is designed to make it easier to access, modify, and generate computer models.  Additional Ejs models for classical mechanics are available.  They can be found by searching ComPADRE for Open Source Physics, OSP, or Ejs.
