conservation of energy - energy cannot be created or destroyed, but can be converted from one form to another such that the total energy before and after energy conversion is the same, energy conversion in electric fan - electrical energy to kinetic energy, energy conversion when diver dives into water - gravitational potential energy to kinetic energy, energy conversion in shooting bow and arrow - elastic potential energy to kinetic energy, step down transformer - mobile phone charger, step up transformer - power station deliver electricity through transmission line, power - = energy / time, unit of energy - joule, unit of power - watt, furnace - where chemical potential energy of fossil fuels converted to thermal energy, boiler - where thermal energy converted to kinetic energy of steam, turbine - where kinetic energy of moving steam converted to kinetic energy of turbine, generator - where kinetic energy of turbine converted to electrical energy, thermal energy trasfers - from a region of higher temperature to a region of lower temperature, energy - ability to do work, chemical potential energy - A form of energy stored in fuels, batteries and food, elastic potential energy - A form of energy stored in objects that are stretched or compressed, electrical energy - A form of energy resulting from the movement of electric charges, gravitational potential energy - A form of energy stored in objects which are placed at a height above ground, kinetic energy - A form of energy that moving objects possess, energy conversion in solar panels - light energy to electrical energy, energy conversion of candle burning - chemical potential energy to thermal and light energy,
