Homework Help: Weight/mass of object on moon/earth

  1. Sep 25, 2007 #1
    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????
  5. Sep 25, 2007 #4
    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
