Which term describes how heavy something is?

Which term describes how heavy something is?

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

Answer: (C)

Weight is the force of gravity pulling on an object's mass, so it describes how heavy something is. The heavier something feels because gravity pulls on its mass with more force, and weight is calculated as mass times gravity. That’s why weight can change if you’re on a different planet with stronger or weaker gravity, while the mass stays the same. To build the idea: mass is how much matter an object contains and doesn’t change with location. Volume is how much space the object occupies. Density tells you how much mass is packed into a given volume (mass per volume). So when you wonder “how heavy is it,” you’re really asking about weight—the gravitational force acting on the mass. For example, a 2 kg mass would weigh about 19.6 N on Earth, but would weigh much less on the Moon because gravity is weaker.
