    Newton universal gravitation formula, how f is dimensionally derived?

    ah I think I understand so by working out the dimensions of G you can show that F must equal to Gxm1xm2 because it will balance the equation to = F?

    Newton universal gravitation formula, how f is dimensionally derived?

    Hi thanks for the help however I focusing on F instead of G giving that G = N m^2 kg^-2 or what G is?

    Newton universal gravitation formula, how f is dimensionally derived?

    It says N (m/kg)^2 so that in dimensions are m x l/t^2(N = Newton = kg x m/s^2??)l^2/M^2)(m/kg^2) so that would mean F = m x l/t^2 l^2/m^2/l^2 how would this cancel out to F which is ml/t^2? Have I got this concept wrong or is there a mistake I am making?

    Newton universal gravitation formula, how f is dimensionally derived?

    If f dimensions are ml/t^2, where does t^2 come from in the equation of F = G*m1*m2/r^2 where I believe G to be a constant, m1 and m2 to be masses and r to be the distance between two masses - so length. To dimensionally analyse this then, where would the dimension time come from if I were to...
