If inertial mass and gravitational mass were NOT the same, gravitation would need to be modified a. b. c. the law of universal Newton's second law would need to be modified all objects falling in a vacuum near Earth's surface would not experience the same 64. To create "artificial gravity" in a cylindrical space station located in deep space, the station is rotated about its long axis. A ball released near the axis, "alls to the wall of the space station. As it falls, the magnitude of its acceleration d. all objects falling in a vacuum near Earth's surface would no longer experience the same force 57.
