Final answer:
The mass of an object refers to how much matter it contains and remains constant regardless of location, while its weight is a measure of the gravitational force acting upon it and varies with location.
Step-by-step explanation:
The mass of an object is different from its weight. The correct answer is c: The weight of an object is the amount of force exerted on the object by gravity while the mass is the amount of matter in the object. Mass does not change regardless of the object's location because it is a measure of the amount of matter in the object, typically measured in kilograms. However, weight can change depending on the gravitational pull at a particular location since it's the force of gravity acting on the object's mass, and is measured in newtons.
For instance, on the Moon, where gravity is weaker, an object will weigh less than on Earth, but its mass will remain the same. In everyday language, people often confuse mass and weight, but in physics, they have very distinct meanings and units of measurement.
