狹義相對論
[來源] (課本習題、考古題、參考書...)
Schutz GR textbook,講狹義相對論的單元,習題:
(第二版 Ch2 exercise 19)
[註]metric (-+++) MCRF=瞬間隨動靜止坐標系
[題目]
→
A body is said to be uniformly accelerated if its acceleration four-velocity a
→ →
has constant spatial direction and magnitude,say a ˙a = α^2 ≧ 0
→
(a) Show that this implies that a always has the same components in
the body's MCRF and these components are what one would call
"acceleration" in Galilean terms.
[瓶頸] (寫寫自己的想法,方便大家為你解答)
如果是只考慮直線運動,那還OK。
要考慮更一般性的,即傳統初速與傳統初加速度不平行時,目前想不到。
