In theories of modified inertia, inertial forces arise from an induction effect of a gravitoelectric field. If inertia has an origin in gravitation, it appears when trying to dissociate the inertial mass from its gravitational field or curved spacetime. Inertial forces come from spacetime resisting a change in the curved spacetime by the rest of the masses. This answers both questions of where do inertial forces come from and why is extra energy required to depart from the path of a geodesic.
