If my mass on Earth is 150 kg, what would my mass be on the Moon, where gravity is 1.63 m/s²?

A. 245 kg
B. 92 kg
C. 750 kg
D. 150 kg

Answer :

Final answer:

Your mass on the Moon would be the same as on Earth, 150 kg, because mass does not change with location. Weight, on the other hand, would change due to the different gravitational acceleration on the Moon.

Explanation:

Mass on the Moon

If your mass on Earth is 150 kg, your mass would remain the same on the Moon or any other celestial body. Mass is a measurement of the amount of matter in an object, which does not change with the location. So, the mass on the Moon would be 150 kg.

It's important not to confuse mass with weight. Weight is the force exerted on a mass by gravity. On the Moon, where the gravitational acceleration is approximately 1.63 m/s², your weight would be less because the Moon's gravity is weaker than Earth's. Using the example given, if a mass of 60 kg weighs 588 N on Earth, it would weigh 96 N on Moon. In your case, your weight on the Moon can be calculated by multiplying your mass (150 kg) by the Moon's gravitational acceleration (1.63 m/s²), which equals 244.5 N (rounded to the nearest whole number would be 245 N).

Therefore, your weight in newtons would change depending on the gravitational pull of the body you are on, but your mass remains constant at 150 kg whether you are on Earth, the Moon, or elsewhere in space.
