Trevor has asked me to post this: it’s a graph matching exercise probably most useful for revision, or perhaps to prove to the double maths students that they don’t know quite as much about mechanics as they think they do! Instructions are on the first sheet. I’ve left it in Excel rather than transferring it all to Word so that you can fiddle with it yourselves. Feel free to modify as you wish. It might also be useful as a ‘drag and drop’ type exercise on the board (or at least bits of it).
