I think the equation for work in (3) below is more
fundamental, but you
could probably also write a general equation for work W as
W = \int_s1^s2{F(x,y,z,t).ds}
where F(x,y,z,t) is the force, ds is the differential displacement in
spacetime, and s1 and s2 are initial and final events. This would
include, not only spatial displacements, but also time
displacements for
work done on 'stationary' particles.
