im a yr 12 physics student and i need a topic for my eei(extended experiemtnal investigation). i need a simple experiemtn that has lots of physics behind it. also i need a topic that is easy to find information on. it would also be good if there were equations that could easily used in the experiment to get my results. last year i chose a really difficult experiment that was really hard to complete, so i want something easy and simple. if anyone has any ideas please let me know. thanks

First give some of your ideas. From a list of ideas it is more feasible to give you help on the strengths and pitfalls of each project rather than present hundreds of possibilities.
