Answer to Question 1

A temporary disturbance of a system is called perturbation, while a more persistent disturbance of a system is called a forcing.

Answer to Question 2

The equilibrium states of a system can be represented as peaks (unstable) and valleys (stable). On disturbance, the system returns to stable equilibrium states but moves away from unstable equilibrium states. A system with a single feedback loop has a stable equilibrium state if the feedback loop is negative and an unstable equilibrium if the feedback loop is positive.
