When a rock is transported from the moon to the earth, which property changes?

The correct understanding is that when a rock is transported from the Moon to the Earth, the property that changes is its weight. Weight is the force exerted on an object due to gravity, and it depends on the gravitational pull of the body the object is on. The Moon has significantly less gravitational force compared to Earth, so the weight of the rock will increase when it is brought to Earth.

However, the mass of the rock remains constant regardless of its location because mass is a measure of the amount of matter in an object and does not change with the object’s environment. Hence, the mass of the rock does not vary when it is moved from the lunar environment to the terrestrial environment.

This understanding emphasizes that while weight can change based on the gravitational influence of the celestial body, mass is an intrinsic property that does not fluctuate with location.
