Final answer:
The weight of an object can change when it enters a region with stronger or weaker gravity. For example, when an object is on the Moon, it will weigh much less compared to when it is on Earth. When people say they are losing weight, they are actually losing mass.
Step-by-step explanation:
Assuming the mass of an object is kept intact, it will remain the same, regardless of its location. However, because weight depends on the acceleration due to gravity, the weight of an object can change when the object enters into a region with stronger or weaker gravity.
For example, the acceleration due to gravity on the Moon is 1.67 m/s² (which is much less than the acceleration due to gravity on Earth, 9.80 m/s²). If you measured your weight on Earth and then measured your weight on the Moon, you would find that you weigh much less, even though you do not look any skinnier.
This is because the force of gravity is weaker on the Moon. In fact, when people say that they are "losing weight," they really mean that they are losing mass (which in turn causes them to weigh less).
