1. The problem statement, all variables and given/known data[/b]
gravity on the moon is only 1/6th as strong as gravity on earth. The acceleration of gravity is 10m/s squared
A - what is the weight of a 26kg object on the earth? answer in units of N
B - What is the weight on the moon? answer in units of N
C - What is the mass on earth? answer in units of kg
D- what is the mass on the moon? answer in units of kg

For part A

1N = 1kg * acceleration of gravity(10m/s)
so 260N = 26kg * 10 m/s squared?

for part B

1N = 1kg * acceleration of gravity (1.6667)

43.3333N = 26kg * 1.6667????

however i am not sure what to do for part c and d

the mass does not change.

wouldnt C be 26kg and D be 26kg????? since the mass remains the same but the weight changes????

### anglum

so in the original problem when it says a 26kg object it means that the mass is 26kg?

and are my calculations correct for part A and B
