This includes the relativistic version of Newton's second law, which shows that F is generally not parallel to a.
- cygx 7y agoBut note that the 4-force is parallel to the 4-acceleration. However, its spatial component only agrees with classical acceleration in the comoving frame. In general, there's an additional contribution that's however smaller by a factor of (v/c)^2.
