Hi there, I have been reading a book in which the author gives me a result of his calculation and I am trying to work it backwards to prove whether he is correct. On July 20, 2005 he states that the combined forces pulling on Earth was 285.8 degrees. He mentions the gravitational formula G*m1*m2/R^2, but instead of squaring he cubes the distance. Its referred to as Resultant Direction or Net Tidal Force. He does this for each planet Sun, Moon out to Saturn only. Can somebody please tell me the steps he took to achieve this result? I think it has something to do with summing the vectors. Any help would be appreciated.
Kindest regards,
Martin.
