Answer:
For example on earth a 70kg person would weigh 686N (70kg x 9.8 ) whereas on the moon, where the gravitational acceleration is about 1.62 , that same 70kg person would weigh 113N. This means on a pair of scales calibrated for earth they would measure 11.5kg. G-force is another name for the acceleration due to gravity
