I have a question over a thing that I've been thinking about lately, and that is why is it that

$$F = -\frac{dV}{dx}$$

where $$V$$ is a potential? I don't remember seeing an explanation for that during my course in classical mechanics.

Go back and look at your mechanics text, or any freshman physics text.
