    Physics Question on gravitation

    Prove that the mass of an object on the moon is 1/6 of that on the earth.
  • #608722
    Ms. Shankar:

    With my elementary knowledge of Physics, I can say that it can be proved that the weight of a substance in the moon is 1/6th of the weight of the same substance in the earth. This is because the gravitational pull of the moon is 1/6th of the gravitational pull of the earth.

    But the mass of a substance remains unchanged.

    Beware! I question everything and everybody.

    I will request that this type of queries may please be shifted to the Ask expert section so that the experienced members can give a detailed answer.
    The concerned editor may please look into this.

    Knowledge is power.

    Mass will be same irrespective of gravitational force. Weight will vary based on the gravitational force. The gravitational force on the moon is 1/6th than that of the earth. So weight will become 1/6th but not mass.
    For example, if you take an object of 100 kg mass the weight of this object will be
    Weight on earth = Mass X Gravitational force on the earth = 100Kg X9.8 m/S2. =
    980 Kg m/S2 or N.
    Weight on Moon = Mass X Gravitational force on the moon = 100kg X 9.8/ 6 m/S2 =
    162.2 N.
    Hope it is clear.
    As opined by Umesh, I also feel these questions should be posted in Ask experts section.

    always confident
