Newtonian model and Einstein's GR are two major models being successfully utilized in Physics. Though these are very useful; their basic concepts are different. In Newtonian model a mass changes movement due to force. Whereas in Einstein's GR, curvature of space-time decides the movement of a mass. Even though these two models are different, i feel these two models can be correlated. These two models can be correlated through my theory. See the question (What is the motion of a particle at any instant of time?) in II.6) of my paper at https://www.academia.edu/31457696/A_Mathematical_Theory_of_Success . Here I answered this question in Newtonian model. My answer is that, this motion at any instant of time will depend on IFS or IRF. If this question is answered in Einstein's GR, the answer would be curvature of space-time caused by the particle at that instant of time. As the motion of a particle is same or common in both these Newtonian Model and Einstein's GR, we can say that there is some correlation between IFS/IRF and curvature of space-time.
