Suppose humans could travel quickly through deep space and are in search of an earthlike planet. A perfect planet is found, with the exception that its mass is huge, such that a human weighing x EarthKilos on Earth (1 G) now feels like he weighs 3x EarthKilos. So the strain on bodily parts might make this planet uninhabitable. And let's assume this new planet rotates once every 24 Earth hours. Would there be any difference in the perceived weight of an object, if that planet rotated every 15 hours, 10 hours, 5 hours, etc. ? Does centrifugal force have an offsetting force to gravity?
