When referring to knowing where to find something when you need it you mean that you do not need a memorization of all things, you just need a source to find it when in need. I hope this answer suited your needs.
The law of conservation of energy is a law of science that states that energy cannot be created or destroyed, but only changed from one form into another or transferred from one object to another.
For example: A bowling ball hitting bowling pins. The energy is transferred and no energy is lost.
I hope this helps :)
