The passage around this formula
For an overdamped particle in a potential U(x,) , an infinitesimal energy balance can be written schematically as . with work associated with changing the control parameter and heat associated with motion through the force field. The distinction depends on the physical protocol, not merely on algebraic rearrangement. Stochastic energetics must also specify a calculus convention when multiplicative noise is present.
