Si un corps (ou atomes) en état de rotation est contraint... Explanation: Si un corps (ou atomes) en état de rotation est contraint de traverser une courbe (trajectoire) 1-gravity wave: Les vagues de gravité (ou ondes de gravité). 2-gravity force: force de gravité. These two gravities are different understandings: A special type of gravity wave is a surface wave, which are the waves you see on the surface of a body of water. A gravity wave is an oscillation caused by the displacement of an air parcel which is restored to its initial position by gravity. <<<< The lifting force is buoyancy, while the restoring force is gravity>>>>. so a few scientists feel they should be called buoyancy waves! We have discussed gravity, but not buoyancy. Buoyancy is defined by Archimedes' Principle: A body wholly or partially immersed in a fluid will be buoyed up by a force equal to the weight of the fluid that it displaces. The buoyancy force is proportional to the difference in air temperature inside and outside an air parcel. http://www.ccrs.nrcan.gc.ca/ccrs/learn/tour/30/30scene3_f.ht... http://www.ccrs.nrcan.gc.ca/ccrs/learn/tour/30/30scene3_f.ht...
