Energy is a conserved quantity; the law of conservation of energy states that energy can be converted in form, but not created or destroyed. 1 of 15 What are the 7 key types of energy? Gravitational potential, elastic potential, magnetic, thermal, electrostatic, chemical and kinetic 2 of 15 What are energy and power measured in? Energy - Joules (J), Power - Watts(W) 3 of 15 Four types of energy transfer? Mechanical, electrical, heating, radiation 4 of 15 What is mechanical work? The force of moving an object 5 of 15 What is electrical work? Charges moving due to a potential difference 6 of 15 What is heating? Energy transfer due to a temperature difference 7 of 15 What is radiation? Energy transfer due to waves. 8 of 15 Work done (Joules) = Force (Newtons) x Distance moved (metres) 9 of 15 Kinetic Energy formula (mass x velocity squared) divided by 2 10 of 15 GPE formula mass x height x gravitational field strength 11 of 15 Elastic potential energy formula (spring constant x extension squared) divided by 2 12 of 15 Non renewable energy stores Nuclear and Fossil fuels ( Coal, oil, gas etc.) 13 of 15 Renewable energy stores Solar, hydroelectric, wave, tidal, wind, geothermal and biomass 14 of 15 Law of conservation of Energy Energy cannot be created or destroyed. 15 of 15
