Capacitors and inductors store energy. The *natural response* of a circuit is what it does "naturally" as its internal energy moves around. We track what happens to voltage and current.

If you connect an external energy source to a circuit its behavior changes. The circuit displays a natural response and a *forced response*. The $\text{RC}$ step response is an example of natural plus forced response.
