Thermal, Kinetic, Gravitational Potential, Elastic Potential, Chemical, Magnetic, Electrostatic, Nuclear Energy Stores. 1 of 20 What happens when a System Changes? Energy is Transferred 2 of 20 What is a Closed System? A Closed System is a system where neither matter or energy can enter or leave. 3 of 20 What is the Equation for Kinetic Energy? Kinetic Energy (J) = 1/2 x Mass (kg) x (Speed)2 (m/s)2 4 of 20 What is the Equation for Gravitational Potential Energy? Gravitational Potential Energy (J) = Mass (kg) x Gravitational Field Strength (N/kg) x Height (m) 5 of 20 What is the Equation for Elastic Potential Energy? Elastic Potential Energy (J) = 1/2 x Spring Constant (N/m) x (Extenstion)2 (m) 6 of 20 What is the Equation that involves Specific Heat Capacity? Change in Thermal Energy (J) = Mass (kg) x Specific Heat Capacity (J/kg*C) x Temperature Change (*C) 7 of 20 What is the Conservation of Energy? Energy can be transferred usefully, stored or dissipated, but can never be created or destroyed. 8 of 20 What is the Equation for Power that includes Energy Transferred? Energy (W) = Energy Transferred (J) / Time (s) 9 of 20 What is the equation for Power that includes Work done? Power (W) = Work Done (J) / Time (s) 10 of 20 What is Conduction? Conduction is the process where Vibrating Particles Transfer Energy to Neighbouring Particles. 11 of 20 What is Convection? Convection is where energetic particles Move Away from Hotter to Cooler Regions. 12 of 20 What is the Equation for Efficiency that involves energy transfer? Efficiency = Useful output energy transfer / Total input energy transfer 13 of 20 What is the Equation for Efficiency that includes power output and input? Efficiency = Useful power output / Total Power Input 14 of 20 What is Non-Renewable Energy? Energy that will Run out one day. 15 of 20 What are some Examples of Renewable Energy? The sun, Wind, Water Waves, Hydro-electricity, Bio-fuel, Tides, Geothermal 16 of 20 What are some Examples of Non-Renewable Energy? Coal, Oil, Natural Gas 17 of 20 What is Renewable Energy? Energy that will Never run out. 18 of 20 What is the Equation for Charge Flow? Charge Flow (Coulombs, C) = Current (A) x Time (s) 19 of 20 What is the Equation for Potential Difference? Potential Difference (V) = Current (A) x Resistance 20 of 20
