Answer:
The weight of a person on the moon is less, compared to their weight on Earth.
Explanation:
Gravitation is a force. Gravity is the force that tries to pull two objects toward each other.
Anything which has mass, also has a gravitational pull. The more massive an object is, the stronger its gravitational pull is. So because the moon iless massive than the earth, you will experience a less gravitational pull and therefore a you will experience less weight on the moon compared to your weight on earth.
EXTRA
The Gravitational pull is difined by the force that arises of masses of two objects in relation to their distance.
Earth's gravity is what keeps you on the ground and what causes objects to fall back to earth.
You can experience a change in gravitational pull on earth yourself, in an exelerating or decelerating elevator.
