Force of attraction need help

  1. Aug 31, 2011 #1
    im looking for a tutorial about an assignment and its says find the force of attraction but i cant understand them.
    here is the problem:
    the teacher gave us this formula f=g x m1 x m2 /d 2(squared)
    g=9.8 m/s2(squared)
    m1=1000 kg
    m2=2000 kg
    d= 2m
    im looking for the force attraction how should i do it?
    Also what unit should i use for this. Thanks a lot


    Just a freshman in HS so its my first time encountering p6. so please help me please.

    Hello again :smile:

    You have everything you need there. All you have to do it plug in the numbers in the correct place.

    HOWEVER, the g in the formula isn't the acceleration due to gravity (9.81 m.s-2) as you have. The g stands for Newton's Gravitational Constant and is usually given the symbol G.
