What equations could you use to explore the dependent and independent variables if I plan to change the length of the pendulums and the distance between them?

This is for just two separate pendulums on a string, not conjoined pendulums or ones with a spring between them. All I can think of is ∆E = mg∆h, v = √2g∆h', t = 2π√l/g' and f = 1/t.
