This is a modelling tool for teaching children about mathematical modelling in Physics. You create visual representations of parts of an equation define relationships between those entities, then it shows visually how each part of the equation moves relative to the others. It also show the data graphically
I took on this project with just the source code and a working example of the program. I managed to compile the code and work out the format to enable me to make changes including adding new screens, fixing existing issues, adding a variety of shapes which show the expansion of the equation elements.
This tool is written entirely in Java, with Swing/AWT as the front end.
