Which quantity is related to the gravitational pull on an object's mass?

• A. Mass
• B. Friction
• C. Weight
• D. Force

Answer: (C)

The main idea is that gravity acts as a force on mass, and the quantity that directly measures that pull is weight. Weight is the gravitational force on an object's mass, described by W = m × g, where m is mass and g is the local acceleration due to gravity. This means weight depends on both how much matter there is and how strong gravity is in that location. On Earth, weight is roughly proportional to mass because g is relatively constant, but weight can change with gravity. Mass, by contrast, is the amount of matter and doesn’t change with location. Friction is a different force that resists motion between surfaces, and force is a general term for any push or pull, not the specific gravitational pull on mass.
