PhysicsEnergyGCSEEdexcel Created by: sharonn.0Created on: 21-04-22 19:06 what are energy stores - magnetic - internal (thermal) - chemical - kinetic - electrostatic - elastic potential - gravitational potential - nuclear 1 of 13 what is nuclear energy The energy stored in the nucleus of an atom 2 of 13 how can energy transferred - mechanically - electrically - by heating 3 of 13 how is energy transferred mechanically a force moving an object through a distance 4 of 13 how is energy transferred electrically charges moving due to a potential difference 5 of 13 gravitational potential energy equation mass x gravitational field strength x change in height 6 of 13 why is no system perfect energy is transferred and some of energy is dissipated 7 of 13 what reduces friction lubrication 8 of 13 efficiency equation useful energy/ total energy x 100 9 of 13 what is conservation of energy energy cannot be created or destroyed 10 of 13 what are conductors a material that allows electric current to pass through easily 11 of 13 what is thermal conductivity measure of how well a material conducts energy when it is heated 12 of 13 how to reduced thermal energy transferred from a warm house walls can be built thicker 13 of 13
