I don't know if this is the right forum to post this, please move it if it's not. I am studying physics at university, and have to prepare a special research project in Lab 1 (Elementary mechanics) by my self and then present it to the rest of the group for a final grade in the course. The type of experiments we do are mostly focused in measuring something (like K of a spring, speed of a mass, frecuency of oscilation, etc) and comparing it to what the theory says about it, by applying error theory to our results (another focus of the course is in learning to use algorithms like linear regression, chi-square, etc.) Now we have to prepare an experiment of our own, and then present results (comparing them to what theory predicts for the case), any cool idea? Some examples may be for example, measuring ficticious forces in a rotating system (hard to put in practice), approaching the value of the acceleration of gravity by some cool method, etc. Thanks!
