Graphs and Tracks Model

Computer Program Detail Page

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).

Acceleration?

This modernized version of Graphs and Tracks has some nice features but excluding an acceleration graph seems like a strange omission.

Thanks, Paul. The model has been updated with the option for an acceleration graph.

4. The Physical Setting

4E. Energy Transformations

6-8: 4E/M4. Energy appears in different forms and can be transformed within a system. Motion energy is associated with the speed of an object. Thermal energy is associated with the temperature of an object. Gravitational energy is associated with the height of an object above a reference point. Elastic energy is associated with the stretching or compressing of an elastic object. Chemical energy is associated with the composition of a substance. Electrical energy is associated with an electric current in a circuit. Light energy is associated with the frequency of electromagnetic waves.
9-12: 4E/H1. Although the various forms of energy appear very different, each can be measured in a way that makes it possible to keep track of how much of one form is converted into another. Whenever the amount of energy in one place diminishes, the amount in other places or forms increases by the same amount.

4F. Motion

3-5: 4F/E1a. Changes in speed or direction of motion are caused by forces.
3-5: 4F/E1bc. The greater the force is, the greater the change in motion will be. The more massive an object is, the less effect a given force will have.
