31Gravity anomaly — A gravity anomaly is the difference between the observed gravity and a value predicted from a model. Geodesy and geophysicsIn geodesy and geophysics, the usual model is the surface of a global spheroid (ellipsoid of Hayford or WGS84) by rather… …
32Quartz crystal microbalance — A quartz crystal microbalance (QCM) measures a mass per unit area by measuring the change in frequency of a quartz crystal resonator. The resonance is disturbed by the addition or removal of a small mass due to oxide growth/decay or film… …
33Mass versus weight — The chains on the swing hold all the child’s weight. If one were to stand behind her at the bottom of the arc and try to stop her, one would be acting against her inertia, which arises purely from mass, not weight. In everyday usage, the mass of… …
