No, I'm reverse-engineering Newton! ;0) F=m*a But, of course, the calculations get complex when dealing with more than two-body collisions using 3D force vectors. And then the center of gravity, moments of inertia, radius of gyration, spring coefficients, and so on might become important. Okay, I'll stop reverse-engineering Endorphin. :)

C makes it easy to shoot yourself in the foot. C++ makes it harder, but when you do, you blow your whole leg off.
