• We called Potential energy stored energy



• *Warm up-"what does potential mean to you?"



• Dictionary Definition: Anything that may be possible



• Energy that is associated with position



• Types of forces:



• Gravitational PE



• Elastic PE



• Chemical PE



• Nuclear PE



• "Energy is the ability to do work(SON!)"



• Potential Energy is the possibility to do work



• Do work on an object to change its potential energy



• Change in PE=The work required to bring an object from intital to final state



• Assume no energy lost due to friction



• Gravitational PE:



• Energy of height



• Increases in response to work done



• Roller coasters, sky diving, skiing, are examples

So that was tuesday pretty much. If anyone has any questions dont hesitiate to not ask me. I have all the notes in my "locker" under my desk. i think this blog thing has some potential to be a good tool if its used right..also has the potential to be pretty funny.
