Hi all, I am not sure if I'm posting on the right place. I am currently working on a computational project. It's about simulating a system with two non-test masses and a bunch of test masses. The instruction sheet says that we should "scale the problem carefully by setting the units such that the non-test masses have a mass of 1 and G, the universal gravitation constant, equals 1." The lecturer did a bad job explaining what scaling really is, and I am not sure what exactly I should do concerning scaling here. Could someone give me a hand?
