Centrifugal Force
The apparent force in a rotating system that deflects masses radially outward from the axis of rotation. This force increases towards the equator and decreases towards the poles.
Centripetal Force
The force required to keep an object moving in a curved or circular path. It is directed inwards toward the center of the curved path.
Equator
The geographic circle at 0 degrees latitude on the earth’s surface. It is equal distance from the North and South Poles and divides the Northern Hemisphere from the Southern.
Poles / Polar
The poles are the geographic point at 90 degrees latitude North and South on the earth’s surface. They are equal distance from the equator. The polar region is considered to be that area between 60° and 90° latitude, both North and South.
