Energy 0.0 / 5 ? PhysicsEnergyGCSEAQA Created by: A_Mah08Created on: 02-10-19 17:40 Name the eight stores of Energy Thermal, Kinetic, Gravitational Potential, Elastic Potential, Chemical, Magnetic, Electrostatic and Nuclear 1 of 16 How is energy transferred? Between objects or between energy stores 2 of 16 Another word for energy transfer? Work done 3 of 16 Equation for Kinetic Store Ke = 1/2mv² 4 of 16 Equation for Gravitational Potential Energy GPE = mgh 5 of 16 How is an object transferred to Kinetic Energy store? It speeds up 6 of 16 How is more energy transferred to the GPE? Lifting the object higher means more energy is transferred 7 of 16 Equation for Elastic Potential Energy? E = 1/2ke² 8 of 16 How is EP transferred to an object? By stretching or squashing an object 9 of 16 Specific heat capacity equation? change in thermal energy = mass * specific heat capacity * temperature change 10 of 16 What is specific heat capacity? The amount of energy needed to raise the temperature of 1 kg of a substance by 1 degree C 11 of 16 Conservation of Energy principle? Energy can be transferred usefully, stored or dissipated but can never be created or destroyed 12 of 16 Equation for Power / Rate of work doing Power = Work done/time OR Power = Energy transfer/time 13 of 16 What is Conduction? Where vibrating particles transfer (kinetic) energy to neighbouring particles 14 of 16 What is thermal conductivity? A measure of how quickly energy is transferred through a material in conduction. 15 of 16 What is convection? Where energetic particles move away from hotter to cooler regions, in gasses or liquids 16 of 16
