Topic 1.7 - Forces and Energy 0.0 / 5 ? PhysicsForces and MotionForces and EnergyIGCSEAQA Created by: Alice CullenCreated on: 20-12-16 12:31 When is work done? Work is done when a force causes an object to move through a distance 1 of 6 When is energy transferred? Energy is transferred when work is done 2 of 6 What causes energy transfer by heating? Work against frictional forces causes energy transfer by heating 3 of 6 What is the relationship between power, work done/ energy transferred and time Power = Work Done ÷ Time 4 of 6 What is the relationship between gravitational potential energy, mass, gravitational field strength and height? Gravitational Potential Energy = Mass x Gravitational Field Strength x Height 5 of 6 What is the relationship between kinetic energy, mass and speed? Kinetic Energy = 1/2 x Mass x Speed² 6 of 6
