There are many useful mathematical tools that use differential equations to model harmonic motion and spring motion in particular. Our goal is to create a new, unique spring model tool that covers a broad variety of spring problems, is easy to understand with a coherent layout, and provides a degree of variability in the external forcing term beyond what existing programs provide. We compared this new tool and several existing ones. Many programs do not allow for external forcing terms, and those that do have put many restrictions on them. We identified mechanisms for entering general external forcing terms and solving the resulting differential equations, and incorporated those mechanisms into our program. The variability of the external forcing term allows this on-line program to solve an unlimited number of different exercises. Finally we looked at various future enhancements that could be implemented in the current program
