PhysicsWork, Energy, PowerASOCR Created by: Robert WassinkCreated on: 07-05-17 20:51 The Principle of Conservation of Energy The total energy of a closed system remains constant; energy can never be created or destroyed but it can be transferred from one form to another. 1 of 8 Energy The capacity for doing work measured in joules J. 2 of 8 Kinetic Energy The energy associated with an object as a result of its motion. 3 of 8 Work The product of force and the distance moved in the directon of the force measured in joules. 4 of 8 Gravitational Potential Energy Capacity for doing work as a result of an object's position in a gravitational field. 5 of 8 Efficiencey The ratio of useful output energy to total input energy, often expressed as a percentage. 6 of 8 Power The rate of work done measured in watts. 7 of 8 Necking When a material becomes longer and thinner at its weakest point after the ultimate tensile strength has been reached. 8 of 8
