1. The problem statement, all variables and given/known data For Year 12 Physics I have to do an Investigation Issue of my choice where we research a chosen topic of our own choice. From want the teacher has explained we will research our chosen topic. Some examples he gave us were "Can a swallow (bird) carry a coconut". 2. The attempt at a solution I sent in an email to our teacher asking whether I could use "Can the surface area affect the rate at which an object moves through water?". However he told me to rethink the idea. I've decided to send in another one which will be "Can a train derail". However I was also thinking about doing something about Maglev Trains however I cannot think of a suitable question. Does anyone have any possible ideas for a question on maglev trains or a suitable physics question for a Year 12 student.
