The Paczyński–Wiita potential is a mathematical formulation used in the study of general relativity, particularly in the context of modeling the gravitational field around a Schwarzschild black hole. It provides a way to simplify the analysis of particle motion in strong gravitational fields by introducing an effective potential.
