Kinemys - Calculator & Tutoring Tool

I have just released a major revision of the web-based kinematics calculator I created earlier this year as part of an art project. This release is all about usability - major reduction of clutter, expansion of the glossary, and clearer instructions on the front page.

Kinemys - http://bit.ly/kinemys
(The display copy in the link is protected to prevent vandalism. You need to make your own copy to use it, which requires a Google account)

Kinemys calculates position, velocity, and acceleration for up to 3 interacting bodies (masses or point particles) and all of the forces acting on them, in up to 3 dimensions. For most calculations you will only need to use a subset of this, but unlike the way you might solve a problem algebraically by stripping it down to the minimum number of equations needed to solve it, Kinemys is designed to show you how each calculation fits into the larger, fully symmetric, system of motion.

Because it is built into a Google Spreadsheet, you can 'Share' your copy of the calculator with a classmate, or someone you are tutoring, and use the built in chat functions to work through a problem together online. The equations used to calculate the outputs are displayed next to them, so that you can follow each step.

The Motion section of each mass calculates the total displacement, momentum, and speed, while the Force & Energy section calculates the kinetic energy, work, change in potential energy, and power, assuming there is enough information to do so. These sections are not as explicit as the kinematics outputs (the equations are in the Glossary), but I may expand them in the future.

Any feedback, suggestions, or questions are appreciated.
