Helium Force

  1. Sep 24, 2009 #1
    I'm not very good in physics but i have something which seems like a basic question only i could not find the answer.
    I'de like to know how to calculate the pushing force of helium towards one kilogram of mass (a vector to the opposite direction of gravity.). For example - one kilogram of helium will apply 5 newtons against gravity vector. Or - for example -t he acceleration will be 1 meter/sec^2..
    To conclude - anything hich will give me indication of how much force wwill it apply.

    Hey Gabriel! :smile:

    You're asking for the buoyant force … see eg http://en.wikipedia.org/wiki/Lighter_than_air" [Broken] :wink:
