Thanks to everyone that commented, it's starting to make much more sense now I've been reading up and done some kitchen practicals! Think I'll have a nice grasp soon. Buffu, I see what you mean with my typo now in post #1, I'd mixed the two equations together, even the screenshot I posted in...

Thanks for all your input, I think I need to learn how to solve differential equations, or at least how to prove something is the solution of one. Probably the same thing :) Just to clear up: \tau=I\alpha \tau=I\frac{d}{dt}\mbox{angular velocity (sometimes }\omega\mbox{)}...

Ah, I'm not at university. I know integration and differentiation, but don't know how to solve equations, I'll turn my attention there, thank you!

I've seen it written \omega^2 in several places though, what makes you say that? Here's a screen clipping of a video from (credit to Dan Fullerton on Youtube) I don't know where \theta=A cos(\omega t) comes from either, but heard there are two uses for \omega in rotional motion?

I'm studying the motion of a physical pendulum, could someone help me make the final step in figuring out how to find the period so I can make predictions before carrying out a practical? Basically I have a meter rule with holes drilled along the length and will be pivoting it at various points...
