Final answer:
Weight is the measure of the force of gravity on an object and can change with location, distinguishing it from mass, which is constant regardless of where it is measured.
Step-by-step explanation:
The measure of the force of gravity on an object is known as the object's weight. This force is dependent on both the mass of the object as well as the strength of gravity at the location where the weight is being measured. Since weight is the gravitational pull on an object, it can change based on where the object is located. For instance, on the moon, an object would weigh less than on Earth because the moon's gravitational force is weaker. On the contrary, mass is a measure of the total quantity of matter in an object and remains constant regardless of location. It should not be confused with weight. Volume is the measure of the space occupied by an object and is unrelated to the force of gravity.
