I have my IB extended essay and i want to do it in physics, now i know how hard it is to get an A on it but I am ready to risk it, my major problem is that its pretty hard to think of a suitable research question. I was thinking of doing it on the effect of temperature on the coefficient of restitution of a squash ball, but that was too simple, so how about if it was about the same topic, but expanded onto different surfaces and compare the gain in rebound you get from temperature on each different playing surface?
