I am an IBDP Y1 student, and we must come up with a topic for our extended essays soon, so we can write them over the summer. I am interested in Physics, but so far we have done only kinematics, the option (engineering), and waves, so there's not much I can do. Our teacher showed us a sample EE (https://www.easthartford.org/uploaded/ciba/Physics_1.pdf), and I found it very interesting. I also want to do something related to rotational mechanics, as it is easier for me, and more interesting. I was just wondering, would I be flagged for malpractice if I do something similar to this sample EE? Of course I won't actually plagiarize it, nor will I copy anything from it. But I do want to do something similar (rolling down an incline, maybe finding the maximum speed, maybe doing smth with slipping). This is a science EE so I'm pretty sure already that if I choose to do this, I will make use of similar formulas, or similar theory, maybe without even being aware of it.
Will this be okay or will it be considered plagiarism by the IB? I really don't want to pick a different topic, as this is my favourite one, plus my only other choice would be waves which is very hard for me. Does anyone maybe know anyone who did a topic similar to what has been done before, and was still fine with it?
