Relative Motion
摘要
Once the physical quantities of interest are defined it remains to clarify the conditions, that observers in different inertial systems—moving with some constant velocity \({\vec v}_0\) relative to each other—can find their observations to be identical. This leads us to the Galilean relativity principle and the Galilei group of transformations. Of special interest are rotating and center of mass systems, which will be discussed in detail.
