An introduction to short term energy storage, time lags, and oscillations

A little discussion and presentation about short term energy storage using simple every-day items.  In mechanical, electrical, thermal, and almost every energy system some items store energy for a short period and release it at a later time.  This causes a delay between the initiation of an action and the result.  (Think applying the brake to your automobile.) 
Very often these items come in pairs with one thing storing the energy by one method and another storing the energy by another method and together these can cause oscillations.   These oscillations have the name "simple harmonic motion".   
This storage of energy will be discussed in depth in future posts on my web site: http://create-and-make.com/
