Is the definition \[\frac{\partial \mathbf{U}}{\partial \mathbf{x}}=\mathbf{F}\] arrived at only by minimising action (that is, using the EulerLagrange equation) and F=ma (that is, is there any other equally thorough way of doing it)?

That is, if you assume \[T=0.5mv^2\] and \[U=U\], and plug this into the EulerLagrange equation, you get \[m\ddot{x}=\frac{dU}{dx}\]. Is this the only fundamental way to get to this equation, or is it only one example of many equally fundamental ones?
