Jacques Posted March 19, 2007 Share Posted March 19, 2007 Or is SR a special case of GR where acceleration is equal to zero ? Link to comment Share on other sites More sharing options...
insane_alien Posted March 19, 2007 Share Posted March 19, 2007 yup. SR is the special case of general relativity where there is no acceleration. you can use either in that case and you will get the same answers. Link to comment Share on other sites More sharing options...

swansont Posted March 19, 2007 Share Posted March 19, 2007 Keep in mind that someone at rest in a gravitational field is considered to be in an accelerating reference frame; it's indistinguishable from accelerating at g somewhere far from a gravitational field. Someone in freefall is not. Link to comment Share on other sites More sharing options...
Dims Posted March 19, 2007 Share Posted March 19, 2007 But what do you mean by subset? The oweral set af cases, including large accelerations and gravitational fields, described by GR. The subset of this set, where accelerations and/or gravitational fields are not large, described by SR. In this sense, the SR is a subset of GR.
