Final answer:
The weight of an object depends on its location due to the influence of gravity. Mass remains constant regardless of the object's location. Weight varies with the gravitational pull of the body it is on, such as Earth, the Moon, or other planets.
Step-by-step explanation:
The weight of an object depends on its location because it is a measure of the gravitational force acting on that object. Unlike mass, which is the amount of matter an object has and does not change regardless of location, weight can vary significantly with changes in gravity. For instance, an object will weigh less on the Moon compared to Earth because the Moon's gravitational pull is about one-sixth of Earth's.
Moreover, weight can also vary slightly on Earth itself depending on your position relative to the center of the Earth. While mass is measured in kilograms, weight should be technically measured in newtons to reflect the gravitational force; however, in common language, we often use the term 'weight' interchangeably with 'mass' and use mass units.
