PhysicsEnergyGCSENone Created by: /Joanne/Created on: 25-02-18 08:41 What is the calculation for kinetic energy? 0.5 x mass x velocity squared 1 of 8 What is the calculation for gravitational potential energy? Mass x gravitational field strength x height 2 of 8 What is the calculation for efficiency? useful energy output divided by the total input energy transfer 3 of 8 What is the calculation for work done? force x distance moved 4 of 8 What is work done the same as? energy transfer 5 of 8 What is the calculation for power? work done divided by time taken 6 of 8 What does Hook's law state? The extension of an object is directly proportional to the force that is applied to it provided that the limit of proportionality is not exceeded. 7 of 8 What is the calculation for Hook's law? Force x spring constant x extention 8 of 8
