damn... the gravitational constant is correct but I somehow (don't ask me why) rep yeah... that totaly helps! to be honest I knew that I had to use the gravitational constant but somehow (bad research) got the equation G = g*m and used that. thanks for your fast answer!

Hello everyone, my name is Harald Tamer Linke and I'm 16 years old. At the moment I'm trying to get a little deeper into astrophysics and for doing such I'm trying to learn some formulas f.e.: the equation for universal gravitation: F = G*(m1*m2/r^2) But my problem is that when I try using this equation for an example, instead of Newton I get Newton/m^2 as result. Here is my equation: The gravitation between two objects (70kg and 80kg) with a distance of 3 meters: F = G * (m1 * m2/r^2) = (9.81N/kg) * 150kg * (80kg * 70kg/(3m)^2) = (9.81N/kg) * 150kg * (5600kg/9m^2) = (9.81N/kg) * 150kg * 622,22..kg/m^2 = (9.81N/kg) * 93333,3...kg/m^2 = 915.600 N/m^2 Can someone maybe take the time and explain my mistake(s) to me? Thank you in advance.
