Graphs and Tracks Model
written by Wolfgang Christian and Mario Belloni
The Graphs and Tracks Model allows instructors to create custom models of a ball rolling on a track with a variable shape. This EJS model was inspired by the Graphs and Tracks program by David Trowbridge. Instructors set the heights of the track segments and the model displays the motion of the ball. Optional displays, including position and velocity graphs, energy graphs, and data tables, can be added depending on the learning goals for the activity. Documents can aslo be added to the model to provide student instructions or activities. The customized simulation is then saved as a new jar file that can be redistributed.
The Graphs and Tracks 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 jar file will run the program if Java is installed.
Please note that this resource requires at least version 1.6 of Java (JRE).
Editor's Note: Students at all levels will be able to explore fundamental principles of motion and force through this "customizable" simulation,
