In objective gravitational reduction of the wave function of a quantum system, the classical
limit of the system is obtained in terms of the objective properties of the system. On the other
hand, in Bohmian quantum mechanics the usual criterion for getting classical limit is the
vanishing of the quantum potential or the quantum force of the system, which suffers from the
lack of an objective description. In this regard, we investigated the usual criterion of getting the
classical limit of a free particle in Bohmian quantum mechanics. Then we argued that how it is
possible to have an objective gravitational classical limit related to the Bohmian mechanical
concepts like quantum potential or quantum force. Also we derived a differential equation
related to the wave function reduction. An interesting connection will be made between
Bohmian mechanics and gravitational concepts.
