Under what conditions is the relationship between mass and weight constant?

ANS: D
Near the surface of the Earth, two equations apply: d = m/v, dw = w/v. In space and at zero gravity, weight is not a factor; at the Earth's core, extreme gravitational forces would increase the weight as mass remained constant.
