Q 9
Question

The weight of an object on the Moon becomes one-sixth of its weight on the Earth. What causes this change? Does the mass of the object also become one-sixth of its mass on the Earth?

Answer
The Moon's weaker gravity causes the change; the mass does not become one-sixth — it stays the same.

Explanation

  • Weight is the gravitational pull on the object, and the Moon's pull is about one-sixth of the Earth's.
  • So the object's weight on the Moon is one-sixth of its weight on the Earth.
  • Mass is the amount of matter, which does not change with place.
  • So the mass stays the same on the Moon and the Earth.
Weaker Moon gravity lowers the weight, but the mass is unchanged.
