Equlibrium

Equlibrium

1. Dynamic

2. Static

3. The tendency of a system to return to its original state after any given disturbance

   • Stable
     • Dynamic
       • When there are constant inputs and outputs of matter and energy, but the system remains almost the same
         • Negative Feedback stabilizes dynamic equilibrium by counteracting any deviation. This acts as a self regulation system. A good example would be when a system returns to its regular state after any change in climate
           • Negative Feedback: When after a disturbance a system returns to its original state and they stabilize precisely by reducing the change applied.
             • FEEDBACK LOOPS
         • Examples: An ant population where the death and birth rates are the same, so even though there are disturbances, the net population is kept the same.
     • A type of equilibrium in which the system tends to return to its original state after a distrubance
   • Unstable
     • A type of equlibrium in which the system forms a new equilibrium after a disturbance
       • Static
         • A type of equilibrium in which there is no change over time. The forces and components stay the same unless there is an external disturbance which would form a new equilibrium.
           • Example: A pile of books sitting over a table, and someone knocks it over.
           • Positive feedback: When a disturbance causes a new form of equilibrium and they destabilize to increase change.
             • FEEDBACK LOOPS

4. RESILIENCE

   • A system's resistance to disturbance, good resilience means a more stable equilibrium

5. TIPPING POINT

   • The point in which a system can not tolerate more changes and it forms a "new" equilibrium
