Question

select the correct answer. why is the weight of an object more on earth than on the moon? a. the moon is a satellite of earth. b. the gravitational pull of the moon is greater than that of earth. c. the gravitational pull of earth is greater than that of the moon. d. the object’s mass is different on earth and on the moon.

Explanation:

• Option A: The Moon being a satellite of Earth is irrelevant to the weight difference of an object on Earth and the Moon. Weight depends on gravitational pull, not the satellite - planet relationship.
• Option B: The gravitational pull of the Moon is actually less than that of Earth. So this statement is incorrect.
• Option C: Weight is the force due to gravity, \( W = mg \) (where \( W \) is weight, \( m \) is mass, and \( g \) is the acceleration due to gravity). The acceleration due to gravity on Earth (\( g_{Earth}\)) is greater than on the Moon (\( g_{Moon}\)). Since the mass of an object is constant, a greater \( g \) on Earth means a greater weight on Earth. This option is correct.
• Option D: Mass is an intrinsic property of an object and does not change depending on the location (Earth or Moon). So this statement is incorrect.

Answer:

C. The gravitational pull of Earth is greater than that of the Moon.
