The Coriolis effect is the rotation of the earth and the movement of a target downrange from the shooter. This is another element that a long distance shooter has to consider for along with wind, rain, snow, distance, elevation and a many other factors. Accounting for all these factors signifies the skill sets needed for precision long range shooting.

The Foucault pendulum or Foucault's pendulum is a simple device named after French physicist Léon Foucault and conceived as an experiment to demonstrate the Earth's rotation.The pendulum was introduced in 1851 and was the first experiment to give simple, direct evidence of the Earth's rotation. Foucault pendulums today are popular displays in science museums and universities.
