Physics Revision 0.0 / 5 ? PhysicsEverythingGCSEAQA Created by: PaulWilliams2002Created on: 12-06-17 20:18 What is Convection? Convection is the movement of heat energy through liquids and gases ONLY 1 of 21 What is the Equation for Specific Heat Capacity? Energy Transferred = mass(kg) * Specific Heat Capacity(j/Kg) * Temperature Change(degrees) 2 of 21 Different types of Energy See page 19 of Revision Guide 3 of 21 What is the equation for Effieciency? Efficiency = Useful power(energy) out / total power(energy) in 4 of 21 How to find Wave Speed? Wave speed = frequency * wave length 5 of 21 What is the equation for Angle of Incidence Angle of Incidence = Angle of reflection 6 of 21 Different types of EM waves Radio waves, Micro waves, Infra red, Visible Light, Ultra violet, X-rays, Gamma Rays 7 of 21 What are Radio Waves used for? For communication 8 of 21 What are Micro Waves used for? Satellite Communication and Mobile Phones 9 of 21 Infra Red waves are used for...? Remote Controls and Optical Fibres 10 of 21 What is the equation for Acceleration? Acceleration = Change in velocity / Time taken ( look at page 44 for triangle) 11 of 21 What is the equation for wieght Weight = Mass * gravitation field strength 12 of 21 What is the equation for force? Force = mass * Acceleration 13 of 21 What makes up the stopping distance? The thinking distance and the braking distance 14 of 21 What is the equation for Work Done Work Done = Force * distance 15 of 21 What is the equation for Gravitaion Potential Energy? Gravitational Potential Energy = Mass * gravitation field * height 16 of 21 What is the equation for Kinetic energy? Kinetic energy = 1/2 * mass * speed squared 17 of 21 What is the equation for Power Power = Work done / Time taken 18 of 21 What is the equation for Momentum? Momentum = mass * velocity 19 of 21 What is the equation for Current? Current = Charge / Time 20 of 21 What is th equation for potential difference? Potential difference = Current * resistance 21 of 21
