Gravitational force
Gravitational force on the Moon is only 1/6 that of the gravitational force on Earth. What would be the weight of a 10 kg object on the Moon and on Earth? What would its mass be on the Moon and on Earth?

The mass of an object is an intrinsic property of that object... that means it is fixed no matter where the object is (on earth... on the moon... or even under water).
The weight of an object is the force required to support that object... that means if an object is placed on the ground, then the force being exerted by the ground on that object will equal that object's weight... and if that object were to be put in water, then the resulting object weight will be less than what it was when placed on the ground. The mass will remain the same in both these cases. Check out this wikipedia article which explains the difference between weight and mass... very self explanatory... Weight - Wikipedia, the free encyclopedia anyway... coming to your question... an object which has a mass of 10 kg on earth will have the same mass on the moon(or in any other part of the universe). But the weight of the object on earth would be the mass multiplied by the gravitational acceleration constant... g=9.8 (approximated as 10 in usual examples) So Weight on earth = mass X g = 10 X 9.8 = 98 Newton. Weight on moon= mass X g(of the moon) = 10 X 1/6 X9.8 = 16.33 Newton. Hope it helps... :) |

When royce was 10 years old, he had a mass of 30 kg. By the time he was 16 years old, his mass increased to 60 kg. How much larger is the gravitational force between royce and the earth at age 16 compared to age 10?
