The gravitational force on Mars is about one-third that of Earth’s gravitational force. If a space probe has a mass of 300 kg and a weight of about 660 pounds on Earth, what would be the mass and approximate weight of this probe on Mars?
A.

mass = 300 kg, weight = about 660 pounds

B.

mass = 900 kg, weight = about 660 pounds

C.

mass = 100 kg, weight = about 220 pounds

D.

mass = 300 kg, weight = about 220 pounds

The mass never changes, but the weight decreases because the acceleration due to gravity on mars is less.

abhisar · Answer

Mass is a constant and intrinsic property of a substance

abhisar · Answer

So as @aaronq said, it never changes !

abhisar · Answer

Weight stands for the Gravitational force exerted on a substance by the earth

abhisar · Answer

So the mass of probe on earth and moon will be the same

abhisar · Answer

Weight on moon will be 1/3 of the weight on the earth

abhisar · Answer

So the correct option will be D
