Lab: Conical Pendulum - Understanding A & Unit

[Helenah]

So I'm doing a lab in class, and when I graphed the Period vs Length of the string, I got it in the form $T=A\sqrt{L}$, but I don't really know what the value $A$ represents nor what its unit is... Can someone help me?

Hello Helenah,

Would you know the answer for a simple pendulum ?

T is time, L is length, so for your A you have [A] = $\rm {time} \; {length}^{-{1\over 2}}$

( So what is the dimenson of 1/A² ? )And: in PF you get in-line math using the tags ## and displayed math using the tags $$
instead of a single $ sign.
