Question

a dog has a mass of 13kg

a. how much does the dog weigh on earth (g=9.8m/s2)?

b. what is the mass of the dog on the moon?

c. how much does the dog weigh on the moon (g=1.6m/s2)?

d. why is g different for the moon and the earth?

Answer 1

A: w=mg    w=13(9.8)    w= 127.4

B: 13kg

C: w=mg    w=13(1.6)    w= 20.8

D: The force of gravity is less on the moon than on earth therefore making the dog weigh less.
