Document Summary

Energy : ability to makes things happen (cid:8869) 4 types of energy : I ] kinetic energy : motion of energy (cid:8869) " k " (cid:8869) mass / speed = kinetic energy. 2] potential energy : stored energy associated with motion (cid:8869) " v " 3] thermal energy : associated with random motions of the atoms that make up a system (cid:8869) " eth" (cid:8869) hot obuelt = eth. 4] chemical energy : potential energy associated with molecular bonds (cid:8869) " ecnem" System energu : sum of all energy (cid:8869) " esns " (cid:8869) + e- ahem (cid:8869) (cid:8869) energy can be transformed into another form of enerau. Ex] " k " v " (cid:8869) energy can be transferred in / out of a system. I ] work : a process that transfers energy to/from a system by mechanical means (cid:8869) " w " 2] heat : a process that transfers energy to/from a snstem by thermal means.
