The conclusion of non accelerated rectilinear motion is that the object will continue to move in a straight line with constant velocity. This is because, according to Newton's first law of motion, an object at rest will remain at rest, and an object in motion will remain in motion with constant velocity, unless acted upon by an external force. In the case of non accelerated rectilinear motion, there are no external forces acting on the object, so it will continue to move in a straight line with constant velocity.
