Question 2 Why is the weight of an object on the moon th its weight on the earth?

Class 9 - Science - Gravitation Page 138

Answer 1

As we know that the mass of the moon is less than that of earth. So it's radius will also be less than that of earth. This is the reason why it exerts less gravitational force on objects. The gravitational pull of the moon is 1/6th of the gravitational pull exerted by the earth. Since the gravitational pull is 1/6th of that of earth, the weight of an object on moon is 1/6th of its weight on the earth.


NOTE-- Mass remains constant while weight can change according to gravitation.
