physics- energy 0.0 / 5 ? PhysicsEnergyGCSENone Created by: fia21Created on: 11-04-14 18:28 identify the 9 types of energy electrical,light,sound,kinetic,nuclear,thermal,gravitational potential,elastic potential,chemical 1 of 5 conservation of energy energy can be transferred usefully from one form to another, stored or dissipated- but it can never be created or destroyed 2 of 5 what do you need to know about useful energy energy is only useful when it can be converted from one form to another 3 of 5 how do you calculate efficiency useful energy out/ total energy in 4 of 5 what do you need to know about 100% efficency no device is 100% efficient the wasted energy is usually spread out as heat 5 of 5
