Query: Work and work-energy theorem in curved spacetime   The definitions of gravitational work as well as work done by the total
external force on a massive probe particle moving in generic spacetime
backgrounds are proposed. These definitions are given in the form of scalar
integrals and thus, are independent of coordinate choices. However, the
dependence on the choice of observer field is essential and inevitable. The
definitions are checked in the case of Minkowski, Schwarzschild,
Reisner-Nordstr\"om and Kerr-Newman spacetimes and agreements with Newtonian
mechanical definitions are verified in the slow motion or the far field limit.
