|
The circumference of the Moon is smaller than Earth, therefore it has less gravity.
|
|
|
The lack of air pressure on the Moon weakens the gravitational force of the Moon.
|
|
|
The mass of the Moon is less than that of Earth, therefore it has a weaker gravitational force.

None of the above

Detailed explanation-1: -Q. Amanda weighs about 600 N on Earth, but would only weigh about 100 N on the Moon. Which BEST explains why Amanda would weigh less on the Moon than on Earth? The circumference of the Moon is smaller than Earth, therefore it has less gravity.
Detailed explanation-2: -The moon’s gravitation force is determined by the mass and the size of the moon. Since the moon has significantly less mass than the Earth, it will not pull objects toward itself at the strength that Earth will. This means that if you went to the moon you would weigh less, even though your mass stays the same!
Detailed explanation-3: -If he was taken to the Moon, his weight would be 100 N. What is the acceleration due to gravity on the Moon? (Take g=10 ms−2) No worries!
Detailed explanation-4: -Since gravity changes, weight changes. The moon’s gravity is one-sixth of earth’s gravity. Hence, weight of the body on the Moon is one-sixth as compared to that on the Earth.
Detailed explanation-5: -Objects on the moon weigh 1/6 of the weight on earth. Hence, the weight of an object on earth is that on the moon.
Detailed explanation-6: -This is because Moon is less massive than Earth. A body’s surface gravity is proportional to its mass.
