most of you will probably know that with a simple bob pendulum, in small amplitude swings,

T=2(pi)x√l/√g


this can be rearranged, calling 2 pi and g: k,"constant", as

T=kx√l (k=2.01)

or T(is proportional to)√l



What I want to know is WHY T is proportional to route l, rather than just l. Any help would be greatly appreciated.

The answer is really quite easy.............assuming you're a physics major which I'm not....

Sorry, I never got up that high

anyone else? i need to know this for my science coursework.

ROFL.

I'm gonna learn that next year, can't wait.

Yea, um, sorry, can't help either. But, try the Physics Forums. Some Quantum Physicists there .

It's not directly proportional to I because of the power to 1/2, which is equivalent to the square root. Try doing the math. If you change the I by constant amounts, the T does not change my constant amounts. The square root matters because it is not a constant acting on the I, it is a power.

Hope that helps a little bit.

thankyou for the link, Flanker

and thanks shenlingstyle.
