Kater's Pendulum Experiment: Accuracy & Procedure

[Lewistbh]

Hi there. I'm doing research for an investigation into various methods of measuring g for my Advanced Higher course (Scottish). I was wondering if anyone knew how accurate this experiment was when compared with a simple pendulum experiment. Also if anyone had diagrams or detailed explanations of the procedure that would be a great help.

Could anyone explain to me how and why Kater's Pendulum works?

Thanks

If I can find my second year lab scripts I'll have a look and see what it says. We did compare it with a simple pendulum and we got much better results.

Thanks, that would be really useful. The harvard link doesn't really explain the way the pendulum works.
