Simple pendulum amplitude

[Bibigul]

How to calculate g if amplitude of a simple pendulum is negligible and the length is known?




T=2π$\sqrt{}l/g$

 

[Doc Al]

In terms of the period? Just solve for g in terms of T and L.

 

[Bibigul]

No, only in terms of L.

Check your problem:
Why should the length L depend on the strength of gravity? This is usually something you just cut to whatever length you like - 1m on Jupiter is the same as 1m on the moon... unless, I suppose, you are doing the measuring from a different gravity from the one the meter is in? (This forum I don't want to make too many assumptions!)
