Effect of the spherical Earth on a simple pendulum

By Lior M. Burko


We consider the period of a simple pendulum in the gravitational field of the spherical Earth. Effectively, gravity is enhanced compared with the often used flat Earth approximation, such that the period of the pendulum is shortened. We discuss the flat Earth approximation, and show when the corrections due to the spherical Earth may be of interest.Comment: 5 pages, 1 Encapsulated PostScript figur
