Energy that is stored in fuel and is released when chemical reactions take place. 1 of 13 What is Kinetic Energy? Energy in a moving object. 2 of 13 What is Gravitational Potential Energy? Energy of an object due to its position. 3 of 13 What is Electrical Energy? Energy transferred by an Electric Current. 4 of 13 What is Thermal Energy? Energy of an object due to its temperature. 5 of 13 What is Elastic Energy? Energy stored in a stringy object when we squash or stretch it. 6 of 13 What is Sound Energy? Energy created from sounds. 7 of 13 Can you lose energy? Why not? Energy cannot be lost, it just changes forms 8 of 13 What tells us that energy cannot be created or destroyed? Conservation Of Energy 9 of 13 What is useful energy? Energy transferred to where we want it to go, in the form we want it in. 10 of 13 What is wasted energy? Energy which is not usefully transferred. 11 of 13 When energy spreads out it becomes..... Less useful. 12 of 13 How do you calculate the efficiency of the device? effciency= useful energy transferred by device (divided by) total energy supplied to device. 13 of 13
