Bohm's causal or ontological interpretation of quantum theory indicates that matter has a well-defined trajectory independent of observers. In this work, the nature of the stochastic process defined by Bohm's momentum is studied for stationary energy eigenstates and nonstationary states in both nonchaotic and chaotic Hamiltonian systems. In addition, Bohm's quantum force is studied for stationary energy eigenstates in nonchaotic and chaotic systems, and for nonstationary states in nonchaotic systems. Based on the results, a conjecture on the nature of the stochastic process defined by Bohm's momentum for nonstationary states in chaotic systems is established.
