Q

What is the definition of an output?

A

A point where something is removed from the system.

17
Q

What is the definition of dynamic equilibrium?

A

Small variations in inputs and outputs within a system can create change, but on average it remains balanced.

18
Q

When will you get a new dynamic equilibrium?

A

When there are long changes.

19
Q

What is positive feedback?

A

This amplifies the change in the inputs and outputs.

20
Q

How does the system respond to positive feedback?

A

The system responds by increasing the effect of the change.

21
Q

What is negative feedback?

A

This counteracts the change in the inputs or outputs.

22
Q

How does the system respond to negative feedback?

A

The system responds by decreasing the effect of the change.
