To determine the weight of an object on the Moon, you need to consider the relationship between weight and gravity. Weight is a measure of the force of gravity on an object, and since the Moon's gravity is approximately 1/6 of Earth's gravity, the weight of the object would be significantly less.

If an object weighs 25 kg on Earth, its weight in a context of physics is actually expressed in newtons (since weight is a force). However, in this case, it’s common to equate the mass in kg with weight in kg for simplicity in such calculations, recognizing that on Earth, the acceleration due to gravity is around 9.8 m/s².

To find the weight on the Moon, you can multiply the mass of the object by the ratio of the Moon's gravity to Earth's. Since the Moon's gravity is approximately 1/6, you would calculate:

Weight on the Moon = 25 kg × (1/6) = 25 kg / 6 = approximately 4.17 kg.

This result is why the answer of approximately 4.17 kg is correct. The smaller weight reflects the weaker gravitational pull on the Moon compared to Earth.
