Show affiliationsWe 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 (FE) approximation, such that the period of the pendulum is shortened. We discuss the FE approximation, and show when the corrections due to the spherical Earth may be of interest.
