What term refers to the amount of matter in an object?

• A. Mass
• B. Volume
• C. Weight
• D. Density

Answer: (A)

Mass is the amount of matter in an object. It stays the same no matter where the object is—gravity doesn’t change how much stuff there is. That’s why mass is measured in units like kilograms or grams and is a constant property of the object. Volume tells you how much space the object occupies, and density is the mass per unit volume (how tightly packed the matter is). Weight, on the other hand, depends on gravity and can change with location, even though the amount of matter (mass) stays constant. So the correct term for the amount of matter is mass.
