How would I know when a Capacitor is needed in an electronics project? Answered

I am just beginning to learn electronics as a hobby. The biggest confusion I have at the moment is how to know when I need to use a capacitor.
What Questions should I be asking my self?
If a capacitor is needed what factors determine the type/size of capacitor I would need?

At this stage in the game, start by working over other people's circuits.

Capacitors are used in places where you need to" hold " some electrical energy, to smooth over variations in it..

Most importantly, the "impedance" of a capactor changes, as the voltage across it varies faster and faster.
