Sorry, I meant to say spinner. I am still struggling to find equations / relationships that could help me link rpm with generated noise frequency but now that I think about it there probably aren't many as the generated noise frequency depends on so many other factors than just the objects rpm...

Ok thanks a lot for replying so quickly. I'll keep looking at what I found earlier that involves sound generation due to turbulence and try and find examples using gyroscopes then.

I am doing a research project investigating the relation between the rpm of an object and the frequency of the sound it generates. The set up is as follows; I am spinning a fidget spinner with a water pressure kit then recording its rpm and the frequency of the sound it creates from its fast...

Thanks @pbuk I like the suggestion of measuring the relationship with orbital period and orbital radius. I'll most likely use that idea for my actual investigation if I get the model to work. But I tested the set up today and I found that as @nasu said and @Steve4Physics valdiated, the friction...

Thanks @malawi_glenn you're right. It's not a scientific model but isn't it still useful? It provides me with a visual representation of gravity which could maybe let me investigate some of its properties like how the central mass affects the orbit of smaller masses. Can I still use this...

Thanks for all the responses. After taking your advice on the fact that an elastic sheet wouldn't be appropriate to investigate relativity I would now be investigating something a bit simpler. My research question could now be related to gravity and orbiting bodies and would be something like...

Ok thanks. I'll think about it this way and I'll try and come up with some ideas.

Hi guys, I am a first year IB student who has to pick his EE topic. The Extended Essay is an independent, in-depth study of a chosen topic within one of the IB subject areas. I chose to do mine on physics. I have to write 3500 - 4000 words for my EE. I've chosen a set up for an investigation /...

Hi guys, I am a first year IB student and I need to give hand in my research question for the extended essay today, the only thing is that I don't really know what I could do it on. The extended essay is basically a 4000 word research project. I was going to do it on photoelasticity, but when I...
