We cannot talk about magnitudes in case of work, but if someone did (-42 J of work) by stopping a moving object. And if someone did 42 J of work, by pushing something, who did more work? Does it even make sense to ask that?
Also, consider Gravitational Potential Energy (GPE), Gravitational kinetic energy of orbiting body (GKE) and Total Energy(TE)
GPE = 2TE and GKE = - TE
If a body is Just gravitationally bound, it takes more energy than if it is moving, to knock it out
But is GKE greater than other two?
