Hi,
I found that action in relativity is written in two ways:
1) S = ∫ ds
2) S= -mc ∫ ds
is (1) for non-relativistic particles and (2) for the relativistic particle ?
why there is a minus sign in front of it?
I read that writing (2) is up to a guess (-mc term), is it very interesting, anyone comment on this?
Thanks
