CHAPTER 5 NONINERTIAL REFERENCE SYSTEMS 5.1 (a) The non-inertial observer believes that he is in equilibrium and that the net force acting on him is zero. The scale exerts an upward force, N G , whose value is equal to the scale reading --- the “weight,” W’, of the observer in the accelerated frame.
