Which term refers to the gravitational force between an object and Earth?

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

Answer: (C)

Weight is the gravitational force that Earth exerts on an object. It tells you how hard gravity pulls on that object and depends on two things: the object's mass and how strong Earth's gravity is at that place. You can think of weight as mass times the acceleration due to gravity (F = m × g). That’s why heavier objects weigh more, and why your weight would be different on the Moon where gravity is weaker. Mass is the amount of matter in the object and stays the same no matter where you are. Gravity is the universal attraction between all masses—it's what pulls objects toward each other in space, not just Earth. Force is a general word for a push or pull, and weight is a specific kind of force caused by Earth's gravity acting on an object.
