If you mean the movement required to bring the arm inward towards the center of the record, yes, tone arm mass comes into play there. But it is a very slow movement, and acceleration is almost zero because the speed is constant. I would expect the force to overcome friction would be greater, and with good bearings, it is pretty small too.
