Homework Help: Weight problem (conceptual)

  1. Jul 5, 2010 #1
    "weight" problem (conceptual)

    1. The problem statement, all variables and given/known data
    an object has a mass of 25kg on Earth. If the same object is moved to an inclined plane in Venus, where the acceleration due to gravity is 8.8m/s^2, how does its weight compare to when it was still on earth??

    a. Wvenus > Wearth
    b. Wvenus = Wearth
    c. Wvenus < Wearth
    d. it depends on the angle of inclination of the inclined plane in venus
    e. it depends on the friction between the plane and the object

    2. Relevant equations
    W = mg

    3. The attempt at a solution
    i'm not sure whether the angle of inclination is to be used here

    i think it's C :p not sure though

    ok last time i got in trouble for just giving an answer so i'll try my best not to give it away here. How do gravity and weight relate? w=mg . . . so what happens to weight after you you change gravity (on earth its 9.8 and on venus its different), how are they related to one another? :)
