Newtonian physics gave a very good model of motion mechanics, dynamics, until the speed of light was approached. Newton's laws are now considered approximations and have been added to by Einstein's model that accounts for near light speed, relativistic dynamics.
The early models accounted for limits known at the time they were developed. Later modifications added to the earlier equations rather than replaced them.
Newton proposed three laws. The second law, force = mass x acceleration, was not limited. However velocity does not increase infinitely.
Newton - Force = rate of change of momentum
Einstein - Force = (rate of change of mass) c
Where c = speed of light.
