Chap 10 Flashcards
Potential energy
energy that has the potential to do work and so the energy is ‘stored’, such 339as gravitational energy, elastic energy and chemical energy
Gravitational energy
Energy in the form of gravity
Elastic energy
Energy in a stretched elastic material
Chemical energy
potential energy derived from chemical reactions
Electrical energy
Electricity
Kinetic energy
Moving energy
Thermal energy
Energy as heat
Light energy
Energy as light
Sound energy
Noise
Law of conservation of energy
In physics, the law of conservation of energy states that the total energy of an isolated system remains constant—it is said to be conserved over time. Energy can neither be created nor destroyed; rather, it transforms from one form to another.
Efficiency //energy
goal to reduce the amount of energy required to provide products and services.
Thermal energy transfer
Heat becoming transformed to other states.
Conduction
Heat tranfered through solid substances fo parti all to particle
Convection
Moves through air particles in vertical circular movements. Only passes through gasses and liquids.
Radiation
Heat moving, requiring no particles to transfer
