Answer
This is a writing exercise for the student, and answers will vary.
Sample 1: What is the mass of a 100-kg person on a planet whose gravity is 1/10 of what it is on Earth?
a. 1 kg
b. 10 kg
c. 100 kg
d. 1000 kg
The correct answer is C. The mass is a property of the object, and doesn't vary depending on its location.
Sample 2: A person weighs 1000 N on Earth. What is his weight on a planet whose gravity is 1/10 of what it is on Earth?
a. 1000 N
b. 100 N
c. 10 N
d. 1 N
The correct answer is B. The weight depends on how hard the planet pulls down on the person. When gravity is only a tenth of Earth's gravity, the person's weight will be a tenth of what it was on Earth.
