According to Einstein's Equvalence Principle inertial mass and gravitational mass are interchangable. If we lived in a universe where these two masses were not equal, how would this translate into everyday experience? For example, if gravitational mass were twice the value of inertial mass would the following be true?: A 1 kg mass is accelerated at 32 ft/s^2 in space. The mass is weighed on a scale calibrated to this experiment and therefore shows the mass to weigh 1 kg. The 1 kg mass and scale are placed on the surface of the Earth (where acceleration due to gravity is still 32 ft/s^2) and the mass is shown to weigh 2 kg according to this scale. Thanks.
