jats:p With the advent of high-accuracy sensors and increased interest in geotechnical centrifuge testing simulating loading within serviceability limits, a stronger understanding of the magnitude and orientation of centrifuge gravity relative to the scale model is necessary. This paper presents a methodology for determining two-dimensional centrifuge gravity within a model independently of centrifuge type or geometry, which can be used to recompose the gravity field from the direct measurement of a single gravity vector, given angular velocity. Finally, the methodology is compared to the mechanics of drum and beam centrifuges to provide physical meaning to coordinate rotation variables. </jats:p>
