Investigating value of g
Posted 06 January 2006 - 02:11 PM
I think the two most interesting ideas I have so far are;
* SHM using various springs and
* Pendulums with the formula g=(4.pie squared.l)/Tsquared
There are a few other ideas, such as simply dropping objects through light gates, but they aren't very original. If anybody knows any good sites for finding out more about this, please post.

- the simple pendulum
- the compound pendulum
- the Kater pendulum (thats a lot of pendulum for one investigation)
- object on a slope ( a= g.sin theta)
- the canvendish-boys experiment to find "G" and then use g= GM/r

tomorrow doesn't matter,
turn that music up,
till the windows start to shatter,
cos you're the only one who can get me on my feet,
& i can't even dance

I don't know about that one-- they may deem it as 'Standard Grade' and let it fail. 5 experiments for finding G?! Wow. Do you need that many? I've got two experiments for my friction experiment, and that's it. Mine seems inferior now. How successful are friction experiments, generally?

I did my first experiment today, it was pretty simple but didnt give good results;
SHM with a spring, where g=x4(pie squared)/period squared
x was the stretch of the spring when a mass was added.
Got 8.7m/s/s, so got to find some errors.

I haven't started my AH Phys investigation. I thought about doing the usuall determine g through various methods but was wondering if there is anything else that is really cool.
