energy transfer Flashcards
what are the forms of stored energy?
gravitational potential, elastic potential and chemical
what is the conservation of energy principle?
energy can be transferred usefully from one form to another, stored or dissipated- but it can never be created or destroyed
when is energy useful?
when it can be converted from one form to another
what is the energy transfer system in electrical devices such as televisions?
electrical energy➡️light, sound and heat energy
what is the energy transfer system in batteries?
chemical energy➡️electrical and heat energy
what is the energy transfer system in wind turbines?
kinetic energy➡️electrical and heat energy
what is the energy transfer system in firing a bow and arrow?
elastic potential energy➡️kinetic and heat energy
what are the types of energy?
electrical, light, sound, kinetic, nuclear, heat, gravitational potential, elastic potential and chemical
