A physicist, accountant (CGA,CPA), and software developer by training, and a professional developer by employment, I wrote my first computer program in FORTRAN w/ WATFOR in high school. Since then I have written device drivers for a PDP-15, CAD/CAM applications in C, and Database applications in everything from FORTRAN (?!) and C to SQL and MS-Office.

I currently build financial and business applications professionally, mostly with VBA / C# / SQL, while developing my own Napoleonics game engine in C# on weekends and evenings.

comment How can I calculate force and acceleration?
Whatever your coordinate origin, provided your coordinate axes are perpendicular to each other (the norm) you can compute and store the X-, Y-, and Z-coordinates of all vectors independently. All three properties (displacement, velocity and acceleration) are vector quantities.

This looks line an X-Y problem. What are you actually trying to achieve through this calculation?

comment velocity of a ball after sliding down a inclined plane?
Why do you say the ball "slides" down the plane, instead of having it "roll" down?

comment Pathfinding Search for Path of Specific Length
@Spinnernicholas: Exactly; That's why I suggested use of Dijkstra rather than A*. If your goal is cost N plus/minus 3, Dijkstra will find all N-3, then all N-2, then all N-1, etc., until finding all N+3. At that point you can make a random selection, possibly weighted, from all suitable candidates.

comment Pathfinding Search for Path of Specific Length
@Spinnernicholas: What do you mean "trend towards cost x"? You can always terminate the Dijkstra's at a chosen upper cost limit.

comment How can I test if an object will “fit” during pathfinding?
@ToddersLegrande: That's a good article - why not write it up as an answer before I do.

comment Are there multiple valid definitions for what translate, rotate and scale do?
When you concatenate a transformation to the existing matrix, is there an option to prepend or append the new operation? You seem to be executing the final two transformations in the opposite order.

Chapters 11 and 18 might be useful. (I don't really have themmemorized - I just looked them up.)

If you have access to a copy of Feynman Lectures on Physics, Volume 1, you could do worse than to browse a few chapters of that.
