Potentiell energi – Wikipedia
Potentiell energi är energi som är lagrad i ett föremål beroende på dess position i ett kraftfält eller lagrad i ett system vars energi är beroende av systemets tillstånd. Ett mekaniskt system som kan lagra energi är pilbågen. När bågen spänns lagras en energimängd (lika med det arbete som krävs för att spänna bågen), vi…
