Scribe Post- January 8th- Tuesday

Last week we called potential energy "Stored Energy".
Potential is defined as things that may be possible or might occur

Potential Energy is associated with position.
Gravitational PE- Gravity
Elastic PE- Elastic Force (Springs)
Nuclear PE- Strong or weak Nuclear Force
Chemical PE- Coloumb Force

Energy- ability or capacity to do work

PE- is ready and waiting to do work
PE doesnt have to actually every happen

PE is stored energy

Change of PE = the work required to bring from an initial state to a final state
(No energylost to friction)


Initial (bottom of the Stairs)
Final (tiop of the stairs)

Gravitational PE
Energy of Height
going up is doing work against the gravitational feild

Change in PE= mg(change in h) = weight * Change in height
Change in PE= 20N * (2m)
Change in PE= 40J


Lets discuss the fact that the beautiful RYAN SHECKLER has been officially named the Breakfast Club Mascot. His rock hard body and hot tattoo are part of the beautiful thing that which is breakfast club. We love him and his amazing eyes along with his precious smile. Ryan will forever remain a part of our first period class. <3
