The Parabolic Throw with Video Model overlays an EJS model on a video of a ball being thrown. The video displays 15 frames per second and a vertical calibration bar. The simulation superimposes a trajectory of a red circle with acceleration x'' = -g, where g is the acceleration due to gravity. The user sets the initial conditions and the value of g in order to match the trajectory shown on the video. This model uses the Xuggle video library and is designed to test the EJS video API. A warning message is displayed if Xuggle is not installed.
The Parabolic Throw with Video 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_ParabolicThrowWithVideo.jar file will run the program if Java is installed. You can modify this simulation if you have EJS installed by right-clicking within the plot and selecting "Open Ejs Model" from the pop-up menu item.
Please note that this resource requires Xuggle.
