Hi,
I've been reading about four-vectors and I have two quick questions:
If the position 4-vector is timelike, are the corresponding momentum and acceleration vectors also timelike? If the position 4-vector is spacelike, are the corresponding momentum and acceleration vectors also spacelike? Why?
Also, I understand the physical meaning of timelike and spacelike intervals, i.e. that if an interval between two events is timelike the events can have a causal link. But what's the physical meaning of timelike and spacelike vectors?
Thanks in advance! :-)
