The former approach is self-stabilising i.e. once a particle's momentum is equal to the force vector, no further change is made to it's momentum. It also results in a non-linear acceleration of particles. The latter approach is simpler and applies a constant acceleration to particles. However, it is not self-stabilising and can lead to perpetually increasing particle velocities. You choose the approach by calling the setForceApplication method.
