Hi! I'm new here, so I apologize on beforehand for any mistakes I may make (grammar/wrong thread etc.). Currently we are doing a project for our exam in my class, and in my group we chose to focus on the following scenario: On a spinning "plate" (you know, like a merry-go-around... sorry, I'm not sure I can describe it better in English, but I think you get what I mean) we follow the movement of an object. Before the plate starts spinning, the object is placed on it in centrum of the plate (which has a shape like a circle). When the plate starts spinning fast enough, the objects should come off at some point. We are now meant to describe the physics of this scenario and we are to come up with the experiments to validate the theories ourselves (why/how does it go off etc.). So any help to get us started would be appreciated (what should we describe/focus on? How can we validate it with an experiment?). Have someone done this before, maybe? Any sources would be much appreciated. I suppose topics like friction, centripetal force, rotation -energy, -mechanics (Newton's laws) and -forces are relevant, and I guess I would also like to include or merely mention centrifugal force and relativity very shortly (just to show them I know about it =)). Our teacher suggested describing the way the object comes off the spinning plate and why and how it goes that way. Also, I thought about calculating the time it would take it to go off or something like that, but I'm not sure how we should validate this with an experiment, so this is where we would like a little help too. I hope I was clear enough, else I would gladly try to clarify. I'm sorry but I wasn't really able to follow the template, because it is not a specific task... I hope it's okay, but please correct me if I'm doing this wrong.
