Question

sue says that an objects weight never changes, and that its weight will be the same on earth and on mars. mark says that an objects mass never changes, and that its mass will be the same on earth and on mars. which students claim is correct and why? a mark, his description of mass is correct as mass will not change depending on location. b neither are correct; they both do not accurately describe what mass is and what weight is. c mark, his argument is better because earth and mars are different planets. d sue, her description of weight is correct as weight will not change depending on location.

Explanation:

Mass is a measure of the amount of matter in an object and is constant regardless of location. Weight is the force exerted on an object due to gravity, and it changes depending on the gravitational field strength. Since Earth and Mars have different gravitational field - strengths, an object's weight will be different on the two planets, but its mass will remain the same. Mark's claim about mass is correct.

Answer:

A. Mark, his description of mass is correct as mass will not change depending on location.
