**General Discussion / Formula For Gravity?**

« **on:**May 16, 2016, 05:15:14 PM »

What formula do you use to calculate gravity? I've read where many people making 2D orbit simulators have trouble using the standard model for gravity. I'm making my own 2D rocket simulator, I had to a linear model for gravity. When I use the standard formula, I can't hold an orbit, which seems to be a common problem with 2D sims. Any advice? thanks
