A Foucault pendulum used to explain the earth rotation is a teaching matearials in many applied physics textbooks. Observers of the North and South Poles easily understand the changes of pendulum motion, but those who are between the poles and the equator have difficulty observing its changes. When we explain some of the changes in the situation of the Foucault pendulum, this paper enables us to give on explanation of them by recognizing the fact that land surface exists on the surface of a circular cone. As a result, a lot of students are satisfied with this explanation of Foucault pendulum motion itself in practical education of applied physics.
