I have a point at which there are (at least) two different forces (gravity to be precise) working. How do I combine those so that the force acting on the point are as realistic as possible?
To put the question into context: I have a small object which is attracted by two other large objects (that's the only direction I look at the problem, the large objects are not attracted by the small object). The force from that attraction is calculated by Newton's law of universal gravitation. So basically I have two vectors which represent those two gravitational forces. Currently I just sum those vectors up, but that seems kind of wrong.
