Question
Which one of the following is a reason why the weight of
a person different on Earth and the moon?Solution
• Weight refers to the force exerted on a body by gravity while Mass refers to the amount of matter in a substance. • The Earth's Moon has considerably less mass than the Earth itself. • Not only is the Moon smaller than the Earth, but it is only about 60 per cent as dense as Earth. • Thus, the gravitational attraction on the Moon is only one-sixth that of the Earth. Hence option 4 is the correct answer. • As the force gravity exerts on a person determines the weight of a person. • A person's weight is generally one-sixth less than their weight on Earth. • One thing to note here is that it is only the value of weight that changes from Earth to the moon, while the mass remains the same.
