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 check if the equation is dimensionally correct and I can't see where it comes from? I do think that it may come from G but i have seen various answers on what the dimensions of G are so I can't cancel the dimensions out to check if it is the same as F? Help would be appreciated, many thanks.
