Document Summary

Textbook: physics for scienists & engineers: a strategic approach plus modern physics (3 rd ediion) Special relaivity is about ime dilaion and length contradicion. Reference frame to be a coordinate system in which experimenters equipped with meter sicks, stopwatches, and any other needed equipment make posiion and ime measurements on moving objects. The galilean transformaions: x=x "+ vt y= y " z=z " All experimenters at rest relaive to each other share the same reference frame. Inerial reference frame is a reference frame in which newton"s irst law, the law of ineria, is valid. The relaive velocity between the two reference frames is constant, with dv dt. Galilean principle of relaivity, the laws of mechanics are the same in all inerial reference frame. +m2 u "1 i: transform the two inal velociies from frame s" back to frame s. The medium in which light waves were assumed to travel was called ether.
