Answer

Answer:

C. The gravity on the Moon is less than the gravity on Earth.

Explanation:

Step1: Define weight and mass

Weight is the force due to gravity ($F = mg$), mass is amount of matter.

Step2: Analyze mass property

Mass is constant, doesn't change with location. So A is wrong.

Step3: Compare Earth - Moon gravity

Gravity on Moon is about $\frac{1}{6}$ of Earth's, not six - times (B is wrong).

Step4: Consider gravity slingshot

Gravity slingshot is for trajectory change in space, not related here (D is wrong).

Step5: Determine correct answer

Since Moon's gravity is less, weight on Moon is less, so C is correct.
