1) A persons Gravity will change if they move from the earth to the moon
2) An astronaut is launched into space. The weight/mass of the astronaut did not change. This is measured in kg. ~ I hope I helped XD !!!
Also just an extra thingy to know/remember :The force acting on them due to gravity is vastly different on the space station than on Earth but their mass will remain the same. ... Weight = mass gravity = 2 kg 10 m/s 2= 20 N.
