===About Mechanical Energy Transfers===
: Any time a [[force]] causes [[energy]] to go from one [[Energy Store|store]] into another, it is a '''mechanical energy transfer'''.
: A '''mechanical energy transfer''' takes place when [[Work Done|work]] is done by a [[force]] over a displacement (parallel with that force).
