This is a totally wide open, undefined question, but I'll answer it anyway! Let's say that "tendency to change" is some function of some parameter, \(f\left(x\right)\). If, for some value \(x\), there is a symmetry about it, i.e.,\(f\left( x-\Delta x \right) =f\left( x+\Delta x \right) \), then it's a extremum, and so it could either be a point of stability or instability. Like a bowl, which could be inverted. Even when it's inverted, it doesn't necessarily mean it'll move---it first has to be knocked off center. The point is, at the extremum, there is no "tendency to change".

Where? In what situation? Unless you give us some more detail, any answers will probably be too general to be useful.

Sure. Think of a boat in water. Boats are usually symmetrical along the center vertical plane.
