Can the term in parentheses of the pendulum period equation be constant?

[8parks11]

Using Newton’s laws, we could show that for some pendulums, the period T is related to the length and free-fall acceleration g by


T=2pi(sqrt l/g)


Can the term in parentheses be treated as a constant of proportionality?

 

[Office_Shredder]

No, because g is always the same, and l varies depending on the pendulum

 

[8parks11]

mathematics, two quantities are called proportional if they vary in such a way that one of the quantities is a constant multiple of the other, or equivalently if they have a constant ratio.

I have graphs of T vs. A, T vs L, T vs m

A=Amplitude
L=Length
m=bob mass

It's a pendelum experiment
I have graphs but how would i explain it in the graph
