Physics P1 2.2 Conservation of energy. 0.0 / 5 ? PhysicsEnergyGCSEAQA Created by: Atlanta and JacobCreated on: 03-06-16 18:52 What is it not possible to do to energy? Create or destroy it. 1 of 11 Energy cannot be created or destroyed but what is it possible to do? Transfer it from one form to another or from one place to another. 2 of 11 What happens to the total amount of energy? It always stays the same. 3 of 11 In all energy transfers the total amount of energy always remains the same, what is this called? The conservation of energy. 4 of 11 How does the conservation of energy apply when an object falls? Gravitational potential energy is transferred to kinetic energy. 5 of 11 How does the conservation of energy apply when an elastic band is stretched? Chemical energy is transferred to elastic potential energy. 6 of 11 How does the conservation of energy apply in a solar cell? Light energy is transferred to electrical energy. 7 of 11 How does the conservation of energy apply in a swinging pendulum? Gravitational potential energy is transferred to kinetic energy and back again as it swings. 8 of 11 What energy transfers take place when you turn on a torch? Chemical to electrical to light and transfer by heating. 9 of 11 In terms of energy, what happens when you burn a fuel? Chemical energy in the fuel is transferred to the surroundings, which get warmer. 10 of 11 *CONSERVATION OF ENERGY IS AN EXTREMELY IMPORTANT IDEA IN PHYSICS SO IT WILL OFTEN COME UP IN EXAM QUESTIONS** **LOOK UP DIAGRAM OF A PENDULUM IN MOTION** 11 of 11
