Transcript
Conservation of Energy • What are all the different ways that $100 could be represented? • • • • • • Cash Checking account Travelers checks Change Gold and silver coins Credit card • No matter what, that $100 will always be $100 Conservation of Energy • Energy will always be energy, no matter what form it is in • Energy can be transferred from one type of energy to another • Potential Energy to Kinetic Energy • Kinetic Energy to Heat Energy • Heat Energy to Light Energy etc….. Any examples? Potential Energy to Kinetic Energy • Most common energy conversion • Roller Coaster- lots of energy transfer going on!!! Potential Energy to Kinetic Energy Law of Conservation of Energy • Energy Cannot be created or destroyed!!! • Energy is always changing from one form to another, but energy is never created and it is never destroyed!!!
