c. The mass and weight of an object on earth are 5 kg and 49 N respectively. What will be their values on the moon? Assume that the acceleration due to gravity on the moon is 1/6th of that on the earth

Best answer

Mass of the substance remains constant. It is the multiplication of density and volume that will remain unchanged in the whole universe. So mass of the object will remain 5 kg anywhere in the universe. Weight has meaning only when an object having a specific mass is placed in an acceleration field, such as the gravitational field .

Weight = Mass × Acceleration 

Acceleration due to gravity on the earth's surface :

Weight = mg

49N = 5 × g

5g = 49

g = 9.8 m/s²

Acceleration on the moon :

1/6 × 9.8 = 1.6333 m/s²

The weight on the moon:

5 × 1.6333 = 8.1665N

Answer is 5kg and 8.17 N
