Hi Richard,

re: this http://en.allexperts.com/q/Physics-1358/2012/10/distance-3.htm

I desperately need an online calculator for Pendulum length and swing time that can also calculate units of swing time converted into circular " Swing Distance " so that I can always quickly obtain the swing "Radius" and prove that;

Pendulum length / Radius of swing circumference = Acceleration of Gravity.

Do you know where I can get one made ?

This is very important.

Thanks so much,

Sharice

A simple pendulum is defined as having a small size weight as compared to its length and a small swing. Under those conditions, T = 2(pi)(L/g)^1/2 where T is the period and L is the length (in meters). The radius of swing circumference is the same as the pendulum length.

Beyond that, I can't help.
