IYPT question on elastic space and need ideas for a hypothesis to investigate

vishnu manoj

I am participating in the IYPT and i have encountered a question on elastic space which relates to gravity wells. I need to get a proper hypothesis that can be investigated within realistic parameters. I unable to get any new ideas because i am relatively new to the subject and dont have much to go on. Here's the question-

The dynamics and apparent interactions of massive balls rolling on a stretched
horizontal membrane are often used to illustrate gravitation. Investigate the system
further. Is it possible to define and measure the apparent “gravitational constant” in
such a “world”?

i wanted to know if i could link my hypothesis with the theories of relativity which could be investigated with equipment from a school lab of course and whether you could suggest some other ideas i should investigate my hypothesis on. It does not necessarily have to be related to gravity wells but related in some way to gravity and their interactions with objects with mass, gravity wells is just something i came up with
Thanks

Do the rules of the tournament allow you to ask help of others?

vishnu manoj

yes the tournament allows people to help others

micromass

Can you link us to the rules which show this?

vishnu manoj

yeah sure just scroll down and the rules will be there in the link provided below http://ilyam.org/FDD_2013_IYPT_Reference_kit.pdf.

OK, it seems to be allowed. Sorry for the inconvenience

vishnu manoj

thats fine but i was hoping someone could give me some ideas for my hypothesis
